Installing a new crankset onto an existing bottom bracket is simple. You don't have to open up the bearings. You do need a crank puller to remove the old cranks if they are still on there.
Unless you're doing something weird like putting a mtn crank on a road bike, etc. pretty much any crank will fit on any bike. The tougher question is will it fit on the bottom bracket you have. Is the BB square taper, octalink, etc.? Also, the length of the spindle (axle) of the BB is usually determined by the crank. So you're new crank may need a different length than your old one.
I'd say either post more specifics about what you have and what you want to switch to. Or visit a bike shop for advice.
