Going from a cartridge-tybe BB to an external cup BB is possible. There is a Shimano one that is press fit, but the others screw in, using the same threads. Have the BB shell faced first, external cups are more sensitive to alignment than cartridge BBs.

Going from a triple crank to a double crank is also possible. Do not require change of BB type, but will require change of axle length to achieve the ideal chainline. If you intend to change axle length you might as well change BB type while you're at it.

Don't really know about the FD. As you're going from a wider range of travel to a smaller range of travel I think the current stuff should work. Maybe not as well as possible, but I can't see any immediate showstoppers. Then again, I've only swapped between 3-2-3 on fairly old stuff. There I've gotten away with just about anything.
