Those are all great to have on hand.
I would also suggest you check the fuse needs for your specific machine and familiarize yourself where each type would be used. I can not tell you how many times I have worked on a machine and they have misplaced fuses (wrong types installed).
A couple switches are also good to have on hand.
But no real need to go part crazy when you have one machine.
Get a volt meter so you can tell if a fuse is out or other assorted power problems.
Have a good time with your first pin. I look forward to reading what your tenth pin turns out being!!
