I thinking of also creating a party of good guys and bad guys.I always have a healer in my party,evil or not.I'm thinking of making an elf Druid for my healer.Should i choose something else.

Druids don't get all the heals that a Cleric does. I'd stick with a normal cleric; maybe dwarven?
Elvin druid? well, they DO get a dex bonus.. but a half-elf druid would be a better choice. why? for starters, you can "raise dead" a half-elf instead of having to cast the higher level (and more expensive) "Ressurection" for elves. Second, they get access to all items used only by elves and humans... cool!
