My garage is really small, and my wife's minivan fits inside. And I need room for my fishing gear and rod-building hobby too, which I spend more time on than cycling. But have most of the above tools listed, but I'll add:

- freewheel remover tools (freewheel vise, 2-pin, 4-pin, splined old shimano, and splined new shimano cassette tools).
- truing stand and dishing tool (portable so I can move it around - not enough space to clamp it to a surface)
- a set of metric and english taps and dies
- traditional threaded headset tools (cup removers, crown race setters, cup installers)
- star nut setter
- sealed cartridge bearing extractor
- about 3 or 4 sectioned tackle boxes or oil proof hobby/sowing boxes for lots of screws, nuts, caps, ball bearings, spacers, washers, etc.
- measurement tools - set of good calipers, tape measure, yd long level (all in dual inches and metric)
- degreaser, rust remover, polishing compound and soaking bucket
- grinding wheel and buffing wheel.

optionally - some expensive stuff
- shop stand with clamp
- spoke threader and or a threader/cutter tool.
- BB face and chase
- Headtube face
- crown race cutter,
- 1" x 24 tpi and 1 1/8" x 26 tpi fork steering thread cutting dies,
- spoke tensiometer,
- frame-fork alignment tools,
- MAPP gas torch for small brazing operations
etc.
