First, a good quality Ti frame should have it's bb shell properly faced and the threads cleanly made by the manufacturer. I have three Litespeed frames and all have been easy to install the bottom brackets with no further preparation.
Second, Litespeed says plain grease on the bb threads is sufficient to prevent seizure or galling. I've used grease, anti-seize and teflon tape all with good results. I prefer the tape as it's easy to use and not nearly as messy as anti-seize.
