Can I get the countdown code and the Gravity templates
from the URC site, or do I have to download them from
somewhere else?
I am assuming you are not a CI as you are in this forum and not the other (if you are a registered CI, you can get them from the dealer site as Darnitol said). URC doesn't officially support the homebrew community per se, although several folks such as Darnitol are very good about helping out as they have time.
To answer your question above, you can find a lot of what you are looking for here:
