Still designing my party. To get all the skills and selected Team Feats, the rules are not well documented and I had to do some research. Apparently, unmodified skill level is what qualifies you for Team feats. Bonuses from abilities, or feats don't count. That makes it a little more difficult to build a party.
I had to drop most of the non-human races to get the skilled feat. Had to shuffle around skills, a bit, but now seem to have skills well covered, skill points left over. Probably need another round of shuffling to further optimize out the wasted skill points.
Global constraints: All members get at least 1 point in concentration to qualify for the Group Trance feat and at least 2 points in survival to get the Camp Routine, Improved feat.

It's not clear if both spellcasters need to take both the magical crafting feats to create both kinds of items with either of their spells. The rulebook and many online references aren't clear on that.
3 evenings of party tweaking and I haven't even started yet. This can be the most fun part for me...
BTW, for reference, a fantastic tool for creating characters and seeing what's possible is the NWN 2 Character Build Calculator
