I bought some cheap screen protectors from Amazon that work great. I also bought a real leather cover from ebay for $15. It even has the magnets in it that turn my HD+ on and off as I open and close the cover.
Rooting is very simple once you feel like you want to do it. There's files on the XDA Developers site that you copy onto an SD card, then just boot from the card. From the boot menu, choose to run the rooter file, and there's one to unroot as well. Shut it off, take the card out and you're done.
