Easily done in a day if you don't have any seized nuts or bolts.
Never use a ball joint tool, just two hammers so no split boots, just get the joint so some pressure is on it then give the mounting a good few whacks and it will pop out, just leave the nut on a few threads so it doesn't shoot out and smack something.
If your going to disassemble your old shocks/springs then you will need a coil spring compressor, if you dont have one then I would spend the money on new top mounts as you wont need compressor when fitting the coilovers, just wind the platform right down so there is no pressure on the spring.
