I am not real good on the nutrition side of things, so I will leave the experts to answer those quesitons.

Glad you found a computer you are happy with. I have the same cat eye as FBG and your dh. I really like it.

As to pedals, I have been spinning and riding my hybrid with spds and look shoes. Since I am keeping my hybrid (need somehting to pull the burley) I looked for new pedals and knew that I wanted something with a bigger platform underfoot. I went with Look Keo peddels and specialized wsd shoes.
