I'm doing the same thing. I finished the game a few weeks ago and have been researching to put together a new party. I went to the "Ironworks Forum" and found links there that have helped a great deal. I found charts on every weapon, spell, and a full write up on all the races including where to put your level points that will advance your party quicker, what weapons they use best, etc.
There is even a spread sheet you can download that you enter in the stats of your spell caster and it will tell you if spells are available to them.
Its been fun just to see all the information out there.
My next time through the game I plan on getting info that will fill the gaps on some of the data including the walkthrough.
I'm sure you will find what you need in all the links at this site..............have fun
