Okay, a few things off hand:
1) player recap, 2) psions, 3) gods
1) The group we've got so far looks like:
Argent: Bard journalist
Jarval: Psion (telepath) copy-editor
Dark Eternal: Psion (dwarven) photographer
Kalanyr: Wizard research assistant
Sixchan: Unknown (don't worry, no rush)
Argent would seem to be the chewy moral center. Kalanyr, utility player, mass distraction device (that 100 XP is there for a reason.

I just want to make sure that for Dark Eternal and Jarval, that you find yourself in a situation where both of you feel happy with your niches: part of this is differentiating your characters a lot (dwarf is a good start, but different attitudes, ways of doing thing, ethics, etc are good as well), and more importantly, different abilities (which suggests under the current look that Dark wants to head away from being the charming type, but I think that was the idea already).
2) Psionics for our psions: I have a PsiHB right here on me, so if you like that, great. If you don't, as some people seem to not to, that's fine as well: suggest something else. If you think there's a clearly better way of handling psionics, then suggest it, and we'll look at it: as long as it seems easily explained, and most of the work is offloaded to you (or you make a really good case to buy it), it'll be fine. I'd prefer that if both of you stay psions, you work under the same system. That sound okay?
3) With regard to clerics (I know Argent has moved away from it, but just in case anybody else): so there are gods, and there aren't. It really depends on your metaphysics, but this isn't a philosophy game, this game eats philosophers for breakfast with a side order of mathematicians (usually with a side order of a psychologist to take the logical edge off) so we'll leave that aside, and just get to the meat of the question: Are there gods?
Virtually all people think there are gods, and wear tokens of the gods they worship, which actually suck life magic from them.
Clerics think there are gods, and wear tokens of the god they worship, which give them life magic.
High-ranking mages and politicians are sometimes agnostic in private, although it is noted in the records that several high-ranking officials who have publicly denied or questioned the existence of the gods usually get smited by lightning bolts shortly thereafter.
High-ranking clerics...well, that's an interesting question what they believe. No one really knows
Traditionally, journalist types worship gods of trickery, knowledge, chaos, and good. If you want god names right now, just give me a bit of time to fix my random Cosmic-Level NPC generator.
