If there is any data on the drive that you want to keep, then you will need to backup first, as all data will be lost during install.

If it's an upgrade, it will modify your machine, it won't overwrite your stuff. It'l even ask if you want to save ME so you can revert back to it at a later date. Just make sure your machine is capable of running XP first. It'll crawl along like a snail on a Pentium III.
Pick NTFS as your new file system - better than FAT32, but you won't me able to go back to FAT32 after it's done.
