How much rapport should I establish?
Should I look for "signals" prior to asking her out, or just go for it?
Objective is to not get shot down of course.

I really don't see the point. A girl doesn't need you to get to know her a lot to go out with her. Some girls are more shy and would like it and most aren't that shy, the best thing to do is make it as casual as possible. Just chat to her and ask her if she would like to hang out some time.
If you want to be more smooth pick a few places beforehand and then bring up something like "I'm a huge coffee drinker" to see if she says something about liking coffee then suggest this place to her and ask if she wants to meet up there.
Just be nice and normal. There's no real method of action aside from that. If you are and she says no then she just isn't digging you that much, no big it happens. :)
