>getting drunk with her and maybe even advancing on her?

I hope you don't mean that in sequential order. Drunken come-ons are the worst. And then you never know if it's something real or just the alcohol.

Just be yourself. React naturally. If you're already established that you like each other, stuff like holding hands is appropriate. Take it slow and watch her reactions.

Umm...I'd stay away from cuddling, too, unless it seems she'd be into it.
