on the back, I can vouch for the Blackburn EX-1, it is a good choice IMO and not too expensive. Ditto for the front with the Nashbar or Performance clones of the old Blachburn Lowrider. All are often on sale at nashbar or performance.

On the Panniers I like the Nashbar or Performance waterproof models. Again inexpensive, often on sale and I have found them plenty serviceable. I like the fact that they are one big pocket and organize their contents in ziplocs. Some folks prefer multiple pockets, but be aware that they do come at the cost of more weight and higher cost. I have also found that the effective capacity is reduced a bit as well with multiple pockets because my stuff doesn't exactly fit the pockets. This is not a huge factor, but is worth considering when choosing the size of the panniers.
