As of last night, compatible or not, all the non-PF stuff is off the table. Third party PF stuff is case by case, I bought a copy of the DSP psionics book and am reading it as I get time.
The two main options I'm looking at right now are deaf oracle/sorcerer/theurge/ (maybe EK or just more oracle/sorc) for CAST ALL THE SPELLS, or going full blasty with sneak attacks, which means probably mostly vivisection alchemist (with maybe a few levels of ninja thrown in for shiggles, can still get +10d6 that way). If I wanted to go utility/crafting/buffing/non-combat traps and such, could go with 1 level of synth summoner to make a body (skill bonuses only, but with good stats), then whenever things go pear-shaped just dismiss the eidolon.
I'm planning to use bloodlines (probably 3-4, maybe more if I want to burn feats) to get extra immunities and such. Rakshasa seems like a no-brainer, giving native outsider type (can resurrect, although it comes so late we'll have true res already anyway) and constant nondetection (screw you, see invis) and alter self. Maestro for all spells Stilled for free and immunity to sonic and language-dependent. Pit-Touched for +6 inherent con, immunity to fire/poison, resist acid 10/cold 10. Verdant for +4 nat armor, tremorsense 30, constant ring of sustenance effect, and immunity to poison/polymorph/sleep/stun. Daemon to remove any effect that allowed a Fort or Will save, and immunity to death effects.
There's just too many good ones spread out over too many focused skills... but very nice abilities, and they definitely seem worth a couple feats each.
