We are finally done with our last 2003 server which also holds all of the FSMO roles.  I am going to be moving these roles to a 2008r2 server this weekend.  Does anyone have any gotchas to look out for?  It looks pretty straight forward.

Yes, it should be quite straightforward.

If you have a 2008 R2 domain controller in place, then all the ADPREP pre-requisites will have been fulfilled. You should be set there.

If you have a single forest/domain (?), the infrastructure master does not play a crucial role so you could always test with that one, or the domain naming master. RID master and PDCe are most critical, the latter even more so.

You can move roles back to the 2003 DCs if you have to:

And if you have AD backed up (which you should regardless), I would give it a shot.

What about issues with Time Server?  I assume that I need to make the new PDCe the authoritative time server?

The PDCe role holder will always be the authoritative time server within the domain hierarchy. You will need to sync it with external time source just like you most probably do with your current PDCe. If you have machines that are not domain joined you should point them to the new PDCe for time.

+1 Evgenij.

Out of curiosity: why not 2012 R2? 2008 R2 is in extended support already.

Believe it or not our main software that we use that is installed on all of the servers does not support 2012 yet.  So when they do finally support it, I am sure I will be doing this again.

Aaah, that makes sense. Sounds like healthcare. I have a few customers like that. These vendors have no clue about the difference between 2012 as an OS and 2012 as AD.
