You don't need to uninstall 2.96-81, you need to upgrade to 2.96-85.  Do this by using rpm -Uvh instead of -ivh.  In general, you can use the -U flag to rpm all the time.

To answer your question, though, you uninstall an rpm by using the -e flag.  Like this:

rpm -e cpp

Note, you don't need the version number, arch, or .rpm extension--just the name.

If you're a complete newbie, you probably don't have much business running a compiler--it's easy to hose things in ways that can't easily be fixed.  But, of course, it's your box...
