Great tips!
No, no one mentioned making sure the bike is level. I have a 2ft level and a torpedo level, no 4ft level. I just went with the assumption that a level on the bike seat means the seat is level for all intents and purposes. Isn't that what we're after (as a starting point)?
It might be worth my while to have my LBS set me op on their trainer and get my seat position set. Assuming, of course, they know what they're doing.

But from a perspective of chasing my tail, it may be worthwhile.
