Haven't had to much time with the Droid X, so I am unsure what the theme should look like. Here's one (for a VERY stable ROM I may add).
releases:sapphire-1.0.0:screenshots:droid_x [CVPCS Sapphire Wiki]
start [CVPCS Sapphire Wiki]
just scroll down to the releases section, choose 1.0 and you're set. It is recommended to flash the stock theme prior to installing a theme ...
OH _ DON'T FORGET TO DOWNLOAD THE GAPPS UPDATE.ZIP!!! OTHERWISE YOU'LL FREAK OUT :)
