Hello, Ryanamur! Glad to see you here
If the information about classes and party's formation is what you are looking for, try to search for the topics like "Best Class", "Who Is In Your Party", "Best Party", "Mages", "Kensai/Mage" or something like these. Usually there are a lot of such threads, since there is NO best class or best party - each one has its own advantages and disadvantages.
So, just look around - and I'm sure, you'll find what you need.
It is really difficult to have something like BEST TIPS regarding classes&parties, because each player has his own style and preferences.
Hope to see you more often here
Have fun with BG2 and good luck!
