If you want to do everything, you will need a lot of tolls that aren't bicycle specific. My two cents is that there is no point in buying Park for anything not bicycle specific. Vessel screwdrivers that fit JIS screws. SK or Gearwrench (or Husky or Craftsmen for cheaper stuff) for combination wrenches, ratchets and sockets. Bondhus or any of several others for allen and torx wenches. And don't forget used tools. My favorite cable crimper is a pair of ancient Bell System pliers originally intended for linesman to crimp telephone connectors.
