Meeting my girlfriend's parents for the first time. How to keep nerves in check?

So, two things:

1. She asked if I would like to come along with her to see her family in early October. That I didn't need to come if I though it was too early. We've been together 3 months.

I said I wouldn't miss it for the world. Her family seem really cool and she's obviously really close with them.

2. She wants us to go on a road trip to a nearby town together when we get a weekend off.

Again, I'm totally up for it and it should be really fun.

My question, however, is about nerves. I know October is a while away, but nevertheless, I really want it to go well. I want to make sure my nerves don't get in the way.

Any advice?
