What downtube42 said about the bottle bosses. They should be on the seat frame, about hip level. Later V-Rexii had the bosses down lower, on the curve of the frame which, although easier to reach, were uglier and less aero. (IMHO.) Owners were expected to melt a hole in the fabric using a soldering iron; that way the hole wouldn't fray.
For trunks, I have an
Angletech Trunk. Angletech and RANS are both good sources. Some people swear by the aero-shaped bags. If you get a big enough bag, you can put a hydration pack in it and run the tube out the top; that way you don't need bottle cages.
