I use solid Carbide. You can often get re-sharpened ones they are cheaper
than new.

With resistors and other compenents it depends on the diameter of the
leads. For most things, including ICs, I use 0.8mm but some require 1mm or
larger. Small diodes will often go through 0.6mm which is the smallest I
use. I also use 0.6mm for vias using thin wire (I don't do PTH)

Ideally some sort of drill press with a precision drill. I put my own
together, largely from scrap, and it has a vice on an X-Y table like a
small milling machine.
I never bothered with anything to back the boards though I know a lot of
people do. Speed should be high but if you get a proper drill it will be
anyway.
