Mind Flayer Illithid Slayer
I'm playing a 13th-level Mind Flayer Illithid Slayer in a Gestalt game soonish, and I've got a build up but I'm thinking of changing it. Currently, it's Rebel (CG Paladin in Fax Celestis's fix) 5//Psychic Warrior 1/ Illithid Slayer 5, but I'd like to rework it to be more of a mobile combatant, running round people and then jumping on them, tentacles extended, and eating their brain.
Available books: Core plus Crystal Keep and possibly homebrew stuff if I can persuade the DM.
Ability Scores: 36-point buy.
Alignment: Chaotic Good, definitely. No compromising here.
Traits and flaws allowed; no manifester/caster levels ect. above ECL (not a problem here, I feel); Practiced Manifester gives extra power points (may not be a houserule, but that's the interpretation of the DM).
Concept:mobile Illithid-slaying Illithid grapple-monkey. Preferably use Illithid Slayer, and would like plenty of size-expansion, and would like high Charisma for Mind Blast et cetera. Anything that takes advantage of flat-footedness would be good, too (I'll be stunning people a lot...).
Concept, reworked: More of a back-line combatant, actually. Would like to stick with Illithid Slayer, but ridiculous Grappling isn't so important- concentrate more on improving Mind Blast and adding a bit more control-style stuff. Also, may swap Psychic Warrior for Wilder.
Other: Gestalt plane-hopping, mainly Material Planes; will be starting soonish, so I need this quite quick.
Obviously, to get the build possible, the first 7 levels are easy...

Take it from there, basically...
EDIT: Going into minute detail isn't necessary, but classes and useful feats are what I'm after. Currently the character can get up to a +34 Grapple bonus (with augmented Expansion), so anything that can get above that is particularly nice.
That Grapple bonus breaks down thusly: +11 BAB +8 Size +8 Gloves of Titan's Grip +4 Improved Grapple +3 Strength. Chaos Monk with the Passive Way style would free up a couple of feats and, at the next level, add another +1 effective to the Grapple (Combat Expertise for 1, so -1, but +2 from the style).
