About the only bolts I might keep on hand are 5mm for mounting racks, fenders & water bottles. Maybe a couple spare crank bolts.
This is pretty much what I buy too. I get bearing balls in packages of 100 in Grade 25 and M5 and M6 bolts which I either buy as the need arises or collect them from replaced components. A do stock brake and shift cables and housing. I buy several cables at a time and housing in 25' rolls.
BTW, are you setting this shop up for your own bikes only or do you plan to so repairs on other rider's bikes? The range of bike you plan to accommodate will have a big influence on what parts you stock
