As for renaming your working catalog, I could have sworn there was an option for it.. however, I can't find it...
So you have a few options here.  First, you could select all of your images, and then "Export as Catalog".  Enter the new name and location, and wait or it to export everything.  Just be sure NOT to check mark the "include negatives", or you'll duplicate all of your images!
The second way is to use the operating system to rename two files. Just browse to it's location (if you're not sure, use file->catalog settings to show you the current one and path to it).  Make sure you have exited LR, then rename the file in the OS.  There are two files you need to rename:  catalog.lrcat, and catalog previews.lrdat.
MAKE SURE YOU SPELL THEM CORRECTLY!    I.e., don't change the extensions.  Just change the names.  You can delete the previews.lrdat if you wish to recreate your preview files.
When you start LR again, it will ask you if you want to create a new catalog or browse to find one.  Select browse, and browse down until you select your new catalog name.  And you're done.
As for backing up, when you hit catalog settings, you'll find settings to backup your catalog.  There isn't a name in that section, but when the backup actually starts (for example, pick "backup next time LR exits, and then exit LR) it will give you the opertunity to choose the location you want to back up the file to.
Cheers!
