It keeps getting harder.
Since you're buying a second hand crankset I was going to say just try to buy the bottom bracket that originally came with it. Unfortunately there are two common bottom bracket shell widths so you have to find the one that matches your bike frame.
Everything on a bicycle works together so it's rare to be able to replace just one component without having to do something else to make it work.
