I like tamiya swabs rather than q-tips for polishing the bore. You need to find the right thickness to fit in there.
Novus 2 is a good polish for the bore. Some folks will use a coarser polish ahead of the Novus 2, like Novus 3 or maybe whitening toothpaste. Some folks will also use a finer polish to finish out the bores, like Microgloss.
If you're running oil, you'll need a sealant to provide an oil-phobic surface on the inside of the bore. For this, go to the auto parts store and pick up some synthetic wax (not carnauba). You can also use Max-Pro Heavy Duty Silicone spray, sprayed on a swab, allowed to "air out" for 15-30 seconds and then applied in the bore.
Edit: Just saw that you're running graphite. In this case, I would not use the Max-Pro, though you might still get some benefit from using a synthetic wax product in the bores before you burnish in your graphite.
