Thanks for the post. It will be interesting to watch.
Having been through the exercize (a garage conversion, not a blog), I can offer a quick suggestion or two. For best service and comfort, as well as atmosphere for your subjects, cover the floor. We simply rolled out inexpensive carpeting, but it made a huge difference.
Depending upon the nature of your subject, consider an overhead support system rather than stands. The garage seems roomy while empty, but lateral shooting space shrinks noticeably by the time you get everything in place using stands. Calumet (lights) and Bogen/Manfroto (backdrop supports) have quite an array, but you can cobble together alternatives if you want to spend less. Check the Calumet site for ideas.
At the very least assemble a selection of carpet remnants to lay across any and all electric cords on the floor to avoid trip hazards. This can be a sincere issue in a narrow space. We use wireless system to replace both the shutter release and synch cords. I can attest from personal experience that neither a tripod mounted camera nor a strobe on a light stand makes a pleasant sound when striking the concrete floor after a trip.
