First off, I want to thank everyone who has put in their two cents. I know the trip won't go exactly as I outlined, but I do feel encouraged that I'm not too far off from my original projections. This is my tentative packing list.
Sleeping Stuff:

Pillow
Sleeping Bag
Tents

Clothes:

Three Bibs
Three Jerseys
two short sleeve shirts
two pairs of regular cargo shorts
six pairs of socks
Sweat Shirt
Sandals
one towel
Cycling Shoes


Hygene:

Toothpaste
Toothbrush
Soap
Small bottle of shampoo
Deoderant
Sun Screen
Bug Spray


Bike Stuff:

Spare Chain
Spare Tire
Chain Grease
Emergency Pump (on the bike)
Six spare tubes
Spoke Wrench


Misc:

Trash bags
Cell Phone/Charger
Plate
Fork
Spoon
Small First Aid Kit
Two Extra Bungee Cords (For Rigging Tent/Sleeping Bag)
Book
Writing Paper
Pens


I'm hoping to fit all of this into two large panniers for the rear of the bike. I don't want front Panniers if I can help it. I think this is doable. If I run out of room, I think I can buy a large duffle bag to put the tent and sleeping bag into, and then squeeze a few things into the duffle bag with them. One might argue that I only need one set of regular clothes, but I want an extra that I can have on hand that way I'll have osmething to wear while I'm doing laundry. Aside from this, is there anything else anyone thinks I absolutely need or don't need?
