Samsung Fascinate :: Battery Drain - Cant Get Camera App To Close

I've had my Fascinate for a week and am having some trouble - actually, lots of trouble with it. Any suggestions are welcome:

1. At night I close out all running programs except Zeam - which I'm using as a home replacement since LauncherPro doesn't play nicely with the Fascinate (too much lag). When I close down I have about 90% left on my battery, in the morning, the phone is dead, battery drained. I typically wake up to about 5 emails and no other notifications so it's not processing a ton of incoming data. I can plug it in at night, but the standby time is supposed to be 312 hours. Am I doing something wrong?

2. I can't get the camera app to close. I sometimes have to pull the battery in order to get it to close. I try hitting the home key and get no response, the back key yields nothing, and the power key won't turn it off. The camera remains functional as I try each of these keys. Even after hitting the power key I can immediately take a picture.

3. GPS won't get a lock. I know this is a known problem, but is it a problem on every device, or is it hit and miss?

I really love the Fascinate's form factor and gorgeous screen, but I'm struggling with whether or not to trade for the Droid X before my 30 days are up. The home key lights, lack of text editing assistance (via trackball, trackpad, or on screen software), lack of LED notification light, GPS issues, and lag are making me lean towards the X. I had an X when they first came out and I never quite got used to the size of it. It never felt comfortable in my hand. But the phone itself worked great. I'd prefer not to have to root my phone to get it to work properly.
