Need Help Deciding Class!

[herrhauptmann]

You still need your saves.
How do you afford a +1 weapon at level 1?
Or get a 3Bab at ranger 2?
Your skills are wrong. As a second level ranger with those stats: 30 points. Youv'e got 39 points allocated.
Include your stat for damage.
You know that when TWF, your attack sequence won't be +8/+7 right?
How are you getting into Darkwood Stalker as a human? It's elf/halfelf.
How are you getting into darkwood stalker at character level 3? It needs 5 bab before entry, so level 6. Also, still missing dodge. (Take a dodge alternate like desert wind dodge or expeditious dodge)

Do you want us to tell you which classes to take you to level 5?

With your stats, you won't see much benefit from Weapon Finesse. Might as well stay with strength and save the feat. Especially sinc eyou still need Far Shot and Point Blank Shot for INvisible blade. (A bad PrC by the way)

edit:
You're very new to D&D aren't you?
BAB prerequisites for feats/classes don't take into account your stats or feats. Just BAB gained from class levels.
