Party composition:
Scout 3/ Ranger 6
Ranger 6/Druid 3
Brawler 9 (slightly modified monk class)
Rogue 5/Beguiler 3/ Shadow Dancer 1
Also a fighter 7 hireling (Tower shielding specialist)
As for deity, probably Pelor using Healing and Good domains but again open to suggestions
However since I'm a paladin and cleric of Heironeous the choice is kinda limited to LG, LN, NG.
As for source material anything except psionics. (even homebrew is allowed if the DM okays it but I'd prefer to keep away from that, this is just a cohort
EDIT: we're gonna play at least another 3 levels if not 6
