How much are you really going to be working on bikes? A lot of these ideas seem like overkill for a home shop. I "support" a stable of eight bikes for myself, my wife, and the kids, and I do pretty well with a table, a workstand, a shelf for lubricants and cleaners, a box for spare parts, and a 2'x4' sheet of plywood nailed to the wall with my tools hung on it. My toolset is based on a "complete" kit I got from Nashbar for about $50, plus assorted things I picked up along the way.
Two things that make a much nicer work area: 1. Good lighting. I go crazy trying to work in poor light. 2. A clean floor. There's nothing more annoying than dropping a small part and then having to clean it again because it picked up a pound of junk off the floor. It's also a lot easier to find things when you drop them if the floor is clean. I guess this also goes for the table and anywhere else you're working.
A lot of bike maintenance is cleaning, and I generally do that in the driveway to avoid dirtying the garage.
