Need experienced advice on a first date at home?

Well, tomorrow night i'm having a girl around my house to just chill out and watch a movie, tele, no big deal.

However, the only girl i've done this with before was my EX, who at that time i was already going out with, so hugging and kissing whilst watching tele wasn't an awkward or uncertain thing.
So Im 21 and this girl is 23, we're both clearly interested in eachother, and she's coming around tomorrow night, i'm not sure how to approach it when she's here, we'll probably be in my room, and the only seating to watch tele is my bed and a chair. Will she be expecting a hug whilst watching tele, or do we just sit there like 2 friends and talk?
I don't have a clue what she expects or what i even expect to be honest?

I'd presume she'd want to kiss me, but it's just getting to that stage, i don't want to seem like someone whos trying to rush everything on a first date in my bedroom!!.

Advice would be muchly appreciated.
