Get Zinn's The Art of Road Bike Maintenance....the first few chapters are all about the tools you will need to get (for various levels of repair, from "basic' to "advanced." If you are starting out with absolutely no tools, then maybe one of the tool kits will make sense. But most folks have some basic hand tools in their basements/garages (hammers, screwdrivers, pliers, ratchet socket sets...esp. metric..., etc.). There are a few "bike specific" tools you will need, like cone wrenches, chainwhips, spoke wrenches, pedal wrenches, BB, rear hub, and crank wrenches, etc. If you're serious, get the best quality you can afford. Poorly made tools are no bargain.
