A set of allen wrenches, combination wrenches, get a set, it's cheaper but you will only use 8, 9, 10, 14, 15, 17mm and probably not all of those. Cone wrenches 13, 14, 15mm, Flat head and Phillips head screwdrivers #1 and #2, pliers regular and needle nose(get a small pair also), diagonal cutters, and a cheap cable cutter. Tire levers and a pump. That should take care of most stuff you will tackle yourself and you can add any of the specialty tools later.
