Nice.
Yep, I originally did mine with simpler tools if I recall correctly. Since then, I have a hydraulic press (no good unless lower arm off the car), but also have a ball joint kit like you have, which I've used for plenty of other jobs aside from ball joints (eg: recently used the cylindrical collars to remove/fit a gearbox rear mount). Mine was from eBay!
EDIT: looking back through my photos, I used the kit I had plus my hydraulic press to fit my lower ball joints. Your may well be more heavy duty but can't quite tell from the pics.
