Flip,
Randy described the process well. You may want to consider trying to determine locations for your subs for better LFE at your primary list. pos. before running Audyssey. Not mandatory, if you are anxious to get to hearing your new HT! \:\) But it can save some additional Audyssey runs in the (near?) future. ;\)

This short two page thread gives a bit of info and you can also search 'sub crawl'. I actually did a reverse sub crawl, which I describe on page 2 of that thread.
