Jennifer,
Gool luck to you and your husband as his surgery comes nearer. It sounds like you are doing lots of prepration before hand.
A word of caution though, don't get dissapointed on the sexual side. It may not work even with the pills right away. You will have to be patient and see what happens. Some men are taking quite awhile on that front. I've been doing great overall at 2 months out from surgery.
It was very hard for me to not do anything I was used to like cutting the grass etc or lifting items. But that 10 pound rule is a good one to follow!
Take care,
Larry
