If u use a rack just set the jumper setting to CS (cable select) so it auto configs it self. Unless you are changing out the Main HD (the one that holds your OS) then no jumper worries. Brands, i use a generic one, not loud at all, just a tiny fan works great fits perfectly. Buy 1 rack and enough trays unless u want more than 1 rack, its all up to your preferences. I personally bout 2 racks and enough trays, so i can swap out mulitipul HD at a time. Most racks are the same except for the metal ones, they cost more. Since your going SATA it is now hotswapable so no need to restart the computer. The adapters should work fine with this application.
here are some racks i see online that i would personally pick out :D
