1. You should use 64-bit so that the laptop can access more than 4GB of RAM.
2. As long as you have an optical drive, you will not have a problem installing Win 7.
3. All the games should be playable at between 1024x768 or 1366x768 resolution. See below link for some benchmarks. Note there could be multiple FPS per game depending on the actual laptop.
