Live wallpapers are just a gimmick JMHO. Not all of them are interactive and the Nexus One wallpaper is blank. I can see where they can become neat eventually but i'm not sold yet.
Yes, this is a nandroid backup ... so first, unzip the contents of the zip to /sdcard/nandroid. Then reboot into recovery mode, choose backup/restore, restore advanced, choose the folder that was unzipped. That's pretty much it. This is a 2.1 ROM, so no uses for 2.0.1.
