Quick tip in case anyone else runs into this. When I first set up my Droid I used my @gmail.com account since my @mattwoodward.com account wasn't associated with Gmail yet even though I was using it as a Google account for things like Google Groups, etc. You HAVE to use a Gmail account specifically to initialize the phone. Note that doesn't mean an @gmail.com Gmail account necessarily, just one that you're using with Gmail.

After the initial setup was complete and I switched my @mattwoodward.com account to Google Apps for Domains, I added that account to the Droid, but in the sync settings screen only Contacts and Mail were showing up as options. There was no checkbox to have it sync the calendar. I deleted and re-added the account a couple of times to no avail.

I started thinking maybe the problem was that I used my @gmail.com account as the "primary" account, though I'm not sure why it wouldn't support multiple calendars. Maybe it does and this was just a glitch. At any rate, I reinitialized the phone to factory defaults since that's the only way you can delete whatever account you chose as your primary account when you first set up the phone. Then when I booted the phone and it went back into the initial setup mode, I used my @mattwoodward.com account and now the calendar sync shows up.

I wasn't using my @gmail.com account for anything anyway and since everything was already in my Google account as far as contacts, etc. are concerned, this wasn't a big deal. I do need to reinstall the applications I downloaded but there were only about three of those to worry about.

More on the Droid later–loving it so far even with this little glitch!
