Magic Items (and possibly build advice) for a Mystic Theurge?

[Italian Hippy]

Good day, everyone.

I just started playing a character with a pretty lenient DM (who just sees my cheesing as a "challenge", some intellectual exercise to see who can come up with the best tactics). The build I'm using is a houseruled Wizard/Ur-Priest/Mystic Theurge. I came up with pretty good stats with random dice rolls. So far I have:

STR: 14
DEX: 17
CON: 16
INT: 18
WIS: 18
CHA: 16

I've started as a human, and I've agreed with the DM to forego the "Evil alignment" and "Spell Focus (Evil)" requirements for the Ur-Priest, instead changing the feat requirement to "Spell Focus (any)". Also, I'm pretty confident I can sucker him into "forgetting" the skill requirements for class entry. Yeah, I'm a crooked player, like Belkar (in fact, I wanted to PLAY Belkar, but the DM vetoed it on the basis of the CE alignment). My current feats are Iron Will, Alternative Spell Source and Spell Focus. I still have to decide on which Spell Focus school to take, advice is welcome.

At the moment I'm level 3, close to 4. My plan is to advance to Wiz 5, then take the first level of Ur-Priest. After that, it's Mystic Theurge all the way to MT 9 (which will give me 9th level Divine spells), and then spend my remaining levels on WIZ. I'll be one level late in gaining 9th level Arcane slots, but I'll counter it by gaining 9th Divine early (as early as CL 14, if I somehow manage to muster enough Wisdom to pull it off, CL 15 otherwise) and being able to prepare Divine as Arcane and vice versa, plus I'll essentially be getting 3 levels in one from the Mystic Theurge advancement due to the rapid progression of the Ur-Priest. Alignment, thanks to the DM houseruling the Ur-Priest, is Chaotic Good.

The stats bonuses I'm planning to get are 1 DEX, 2 WIS and 2 INT, although I still have to determine the exact order. I'll probably upgrade DEX first, then WIS and lastly INT, although I plan to procure stat-enhancing items along the way.

Level 20 CL is going to be 19 for both classes. Due to the buildup of the group (one VERY BAD druid, one Ranger and 3 rogues) I had to fill the roles of both Arcane and Divine caster.

What I would ask of more experienced players is: which Magic Items should I aim for? Unless something is obscenely overpowered, I think I should have no problems in making anything fly at this table, plus the world is a "magic-mart" one (pay gold, obtain magic). At level 3 I'm looking at the Handy Haversack and the Blessed Book at the moment, but what about advice for subsequent levels? I'm trying to plan way, WAY ahead.

Also, if you have any suggestions to improve my build, feel free to give them. Even after the first session, I have established myself as the tactical mind and the "leader" of the party easily. I don't think the DM is going to veto much to his strongest and best party member and roleplayer. Please just don't suggest straying much from the path I've already planned for, stuff like Fochlucan Lyrist and Sublime Chord are way out of my league for the way I developed the character.

As a sidenote, in a homage to Tsukiko, I've made my MT have eyes of two different colors :)

Thank you in advance for your time!

Do not sucker your DM: play nice
Trade away familiar for any of a numbe of things, regain it via a feat (that way you get full familiar power)
Feat at 1st: Academic Priest, now you are Int SADish
Get the CL+2 ability, some armor prof, and make all your spells divine as you stand protected in a metal case

Go for the Cloistered Priest variant from UA. Then I recommend, in the way of items, anything that raises your CL. I agree with the feat suggestion above.

"Any of a number of things"? Could you elaborate? Anyways, I don't generally use familiars, I don't like the concept that much. So far I haven't even chosen one.

What does "SADish" mean? I'm assuming Academic Priest lets me use my INT instead of my WIS as the main casting ability for Divine spells.

CL+2 ability? Which one is that? Making my spells divine would entail the use of Alternate Spell Source though, which sets me back one feat. Armor proficiencies, I can't really get without dipping either in a non-caster class, wasting a feat or using Cleric instead of Ur-Priest (which would make level 9 Divine spells unattainable).

Also, items?

Sorry, missed the level selection piece myself. Anyway, apart from Academic Priest, you should probably look into getting items that boost your intelligence (Tome of Clear Thoughts, anyone?). That alone should probably be worth your entire WBL.

Imbued staff, eidetic spellcaster, specialist substitutions, focus caster...

-ish in that the divine side's save DCs are still keyed off wisdom

Well since you say "lenient DM" ask about MT up to 20. You can then get nines on both sides.

Items:
Pearls of Power
Fort save boosters
Metamagic rods
Spellblades of dispell magic and the like
Headbands of Intellect
+Concentration items
Artificer's Goggles
Scrolls of Uncertain Provenance

Maybe I wasn't clear, but I don't know what "SAD" means in the context. :)

Practiced Spellcaster would be nice, I will look into that. MT to 20 is unfortunately not an option. A bit of tweaking (like for the Ur-Priest) is okay, completely reworking the rules is not. Plus, Wiz5-Ur1-MT works pretty well for a mid-level fast power increase, and Ur-Priest only gets up to 10. Going a classic WIZ/CLE/MT would be quite the slow bloomer...

Single Ability Dependent as in you only need one ability, Int in this case

Oh... Thank you :)

Oh... Thank you :)

You should note it doesn't change some aspects of the class, like relying on wisdom for saving throws against your Ur-Priest spells.

Well, considering that at the moment I have a full 18 in both WIS and INT (and the feat can be taken only at level 1), it might be something I could consider for another characters in the future, although I don't see myself playing another Divine/Arcane dual progression class anytime soon, but thanks for the advice anyways.

What's so good about the Scrolls of Uncertain Provenance? From the description I found they don't seem to be *that* incredible.

[Gildedragon]

You have high int; thus you can make good use of knowledge checks to identify enemies (and their resistances, weaknesses, and attacks)
The scrolls provide a hefty bonus, add to that the kn dev feat and your weapon like spells are likelier to hit.
Also critter ident benefits your allies as you can tell them what you learn
