For the most part, selecting your bicycle tool kit will be most critical with regard to the bottom-bracket design you have. If you have a cassette instead of a freewheel, you may yet need another special tool. China mountain/road bikes like mine usually have a freewheel.
I've worked on cups like that. In my experience, a special tool isn't needed unless the cup is good and stuck. The distance between the flats is just a bit more than the diameter of the axle, so you can slip a big Crescent wrench over the whole thing and get some purchase on it. And, since it's the adjustable cup, there's no real torque involved unless the threads are rusted and frozen. I've dealt with persuading stubborn cups by holding the wrench on with a large socket or washers and a bolt, and giving it a good whack, or leaving the wheels on and pushing down with my foot.
That's a case of wait and see if you really need the tool.
