Hi rhfjr!
When you insert the 2003 CDROM you get the choice of either updating
your existing version or retaining it.
Most users, I think, choose to update but there are no real problems
associated with having more than one version on your computer as long
as you have plenty of spare hard drive capacity.
[for the sake of completeness only] ... and you install into a
different folder from the Office 2000 installation (which has been
simplified a little in 2003 reletive to previous versions), and you
install from oldest to newest (as you would be doing), AND you decide
which version of Outlook you want to run since that's the only Office
application that you can have only a single version of. (Personally I
like Outlook 2002 better than 2003 now that I've learnt to harness the
power of the task bar, but to each their own.)
All the gory details can be found here:

But of course, most people don't need multiple versions, and as Norman
said they'll choose to just let the Office 2003 install program take
care of updating (eliminating, effectively) the previous version for
them. I would, however, recommend that before installing 2003 you at
the very least back up:
- your personal.xls file if you have one;
- any .xlt (template) files that you may have created (as well as .dot
files in Word);
- Any .pst files from Outlook. (Unless your e-mail is on an Exchange
server, in which case you don't have to worry about that part.)
