Homer, it sounds like you are all set for 7.1 except for the surround speakers. You can get excellent surround speakers at a moderate price by concentrating on high quality midrange and tweeters. Don't worry about the bass; it's not that important for movie surround speakers. Forget Bose speakers; they don't have any detail.
I would still recommend a second sub and put both in corners. Most HT that I have seen have a loose boomy bass that turns me off cold. Placing the subs in corners make them produce sound that you feel in your chest.
