So I have just recently unlocked the drow and I've been trying to decide weather I want a sorc or wiz first. I think I'm going wiz so I can get an idea of what spells I want to take. So I have a few questions for all you wizzys out there

1) Should I max out int at 20 during creation?

2) At what level should I take what feats?

3) As a wizard do I need to increase my UMD? or does that come standard?

4) Is there any items that are good which should effect my starting alignment?

I think thats it for now, I'm sure I'll come up with some more. Thanks for any support.
