The idea behind researching all branches of magic is that while you might specialize in one, you can use all of them. Also, it's easier to work things in Civ 3 that way, I think.
As for "good" guys using "evil" races, think of it this way: Your people are going out and swaying a certain segment of a race to see things your way, and fight on your side. In general trolls or dark elves or whoever are just like the rest of us: they go to their jobs every day, then go home and play with the little trollings, hit the wife over the head with a rock (a troll kiss), and do normal troll things. Just because they happen to have a taste for human flesh, that doesn't make them Evil, just diverse in their cuisine choice. You're there to make sure they only eat the flesh of the OTHER guy!
Hope that helps in the understanding department. Happy playing!
