2 - Crank puller and a lot of HTFU to get the cranks off
3 - I'm unsure of what BB you have so I don't know what BB removal tool you'll need. You might need a lockring tool if it's on tight and most likely one of these
Might be cheaper to get your LBS to do it unless you plan on doing it to any other bikes.
Reverse the process (without he crank puller obv. to fit the Sugino 75 BB and cranks.
