I've been using Joe Friel's "The Cyclist's Training Bible" to set up my routine. It explains periodization pretty well. I've found that even if I don't stick to it exactly, it helps me keep focus what I should be working on. Instead of Crits and TTs I set my calander up with centuries and other rides.
I usually get four days of riding in per week. Two one-hour sessions during the week (either a trainer or short ride). I use those to work on specific techniques. On the weekends I do my longer rides - fat burners and endurance.
Ed Burke's "The Complete Book of Long-Distance Cycling" is a good reference for doing centuries and long rides.
