Okay. Push it to your sdcard. You can put it anywhere (if I'm not mistaken) and install using either clockwork recovery (using the install .zip option) or rom manager (install rom from sdcard option). Make sure to wipe data and cache. Always backup incase of failure. Restoring system settings I am not sure on that, but to my knowledge, it can't be done (I could be wrong on that). As for titanium backup, it works just fine. I am still fairly new as posted before, which means I could be wrong on any of this. I am currently using UD, and have had no issues thus far. Hope this helps any.
