The fuel pump is in the engine compartment with an aux under the car. I originally planned on making a plywood bottom and attaching the carpet to that so that I could lift it to access all of the bolts for the gas tank, but I ended up cutting a small X in the carpet over each bolt head (it is not glued over each bolt) so that I can still access them, because I do hope to put a new tank in within the next year, and it doesn't show that way. This was my first attempt at carpet, and it wasn't overly difficult. Basically I just measured each area to be carpeted and cut the material, adding a few extra inches all the way around. Next I dry fitted to get it a little closer, then glued and worked it into all of the grooves/corners with my fingers. After letting it sit for about 1/2 hour, I trimmed off the excess with a razor blade (these don't last long cutting carpet and you do need fresh sharp ones about every 2 feet of cut). Getting it to form fit wasn't as difficult as I expected. I did learn that it is key to get enough glue on the edges and around any of the ridges, but not to put too much, as it will just come undone.
The carpet I used came in a 3x6 roll and was available in black, medium blue, charcoal, or beige. My local store only had one roll of the beige in stock, so you may need to plan ahead.

As far as the water goes, I did use a tube of body sealer to seal the holes/joints in the trunk before carpeting ($8 I think), and I plan on putting new weather stripping all the way around. I don't drive my B in the rain (it’s not my daily driver) if it is at all avoidable, and the only car wash it gets is a hand wash at home. Thanks for all of the compliments and thanks to all of the "gurus" on here that have offered advice. It is your many bold projects and grand undertakings that inspire me to take a chance and try something that I haven't done before!
