www.julesborel.com is also a good source and can be a little cheaper than Otto Frei's.
Other tools you need for basic work:
Screwdrivers (don't skimp, get A&F, Bergeon or Horotek)
Tweezers (Get some pretty decent ones, its worth it)
Oils and Oil pin (La Perle oil is cheap and good for reps)
Hand remover
Hand setter
Rodico (super handy, removes finger prints, hold small parts, must have item)
