Okay, at home, cracking open the books.
Two-Gun, I'm afraid you can't play Earth Genasi as written. I'll explain why.
Let's compare Aasimar to Earth Genasi. If you have the books, you'll see that they're very similar. They both have darkvision; they both have about-equivalent (i.e. borderline-useless) 1/day spell abilities, and the same land speed. They both have a +1 Level Adjustment. So. The Earth Genasi's remaining abilities--+2 to two physical stats, -2 to two non-physical; Fighter FC (goes well with stat adjs); +1 resist vs Earth spells/5 levels; and...oh wait. That's it. (Besides another limitation that only applies to clerics.) To compare with the Aasimar's: +5 resist to 3 energy types; +2 bonus to two stats with *no* penalties; and +2 bonus to Listen and Spot checks.
Umm...I don't think so.
So. Two-Gun, here's my offer to you: roleplay the flavour text for the Earth Genasi to the hilt, and you can have the race without the +1 LA! Can I assume you're playing the warrior role? Let me know that, at least, and I think I'll retract my earlier posting about not fixing slots until chars are received; the four of you at least seem pretty certain about what you want to play.
Mithran and Sorrow, your chars are fine. Particularly if Two-Gun goes warrior as I think he's headed, the two concepts for the arcane casters will likely complement each other well. No worries there.
Voadam, I've checked the CW and Nature's Warrior and Warshaper are fine. Interesting way you're heading; I'm going to class you as a warrior/priest MC with that. So I think the party should have another priest (or MC priest) just in case.
--Which brings me to the final point of this post. Dr. Anomalous and Soulforge, I haven't heard from you since you said you were interested. Which means you get to fill in the holes! : ) Assuming Two-Gun does go warrior, one of you will need to play a thief-type, and the other some sort of priest. Please get back to me with your ideas as soon as possible.
