Yeah, don't overthink it. My first date was with a guy before either of us could drive, so his mom took us to the movie theater. I made several mistakes on my first date:
-- Letting his mom pick us up in her station wagon full of Rottweilers. They were in the back and we were in the second seat, so I had Rottweiler slobber all over the back of my shirt by the time we got to the theater.
-- We saw "Blazing Saddles." I was in ninth grade, and although I'd seen it before, my date hadn't. For anyone who's seen that movie, you can probably understand why seeing it with a first date in ninth grade probably wasn't a good idea. Do you *laugh* at Lili Von Schtupp or not?
But it was a nice, innocuous date. And I look back on it fondly.
First date with current hubby (at age 37) was quite a different matter. Met on the internet and were finally meeting in person. I went home in my car afterwards (we had dinner, that's all) crying my eyes out (tough to drive like that!), saying I'd never go on another blind-type date again. Married him a little over a year later. SO, although first impressions might mean something, don't put too much stock in 'em.
Oh, and I definitely agree. No hanky panky. Sheesh. It's a shame we have to even say this. I agree with the "Happy Feet" idea too. No date movies. Too much pressure. Go for a fun comedy like that. Remember: You can't unsay something, and you can't go backwards. Slow and steady wins the race in dating. Don't try to impress her. Just be you. If you falsely impress her now, she'll just figure out who you are that much later anyway. Better she gets to know you right up front.
And have fun!! And don't post all about it on your blog when you get home.
