I got a couple things I really loved in Amsterdam.

1. Check out the Rijksmuseum. Go to the Van Gogh museum if you have time as well!

2. Take a canal boat tour of Amsterdam. It's really nice and you can get some good pictures. See my thread on Beautiful Amsterdam.

3. The sexmuseum. Especially with the girlie it'll be a good time!

4. There's a local restaurant, I wish remember the name, serve local stampot. It's really good, expensive, but a nice place to take your girlie!
