So now that I've punched holes in my walls to fix the galvanized pipes, I'm
wondering what is the most accurate way to repair the drywall.
I cut most of my holes using a punch saw, just jab it in and cut the holes,
but is it more accurate and elegant to use a knife when cleaning those
holes? Also when repairing, is smaller better, that is is the smallest hole
you can cut to clean the drywall the best or is a larger hole easier to work
with?

depends on the size, but yes a razor knife is best to get a good cut. I
usually cut a patch bigger then the hole you made, trace it onto the wall,
cut it out with a razor knife, place a couple of piece of wood behind the
hole bigger then the hole, use a screw to hold them onto the wall then place
your patch in place with screws and tape it and use mud over the tape, let
dry and sand.It takes some practice but it sounds as though you have plenty
of holes to get good at it.

Oh yes I'll be getting good at it alright. The previous owner had a dog who
he kept confined in the garage. The dog pretty well ripped the heck out of
the drywall (and the door frames, garage door, bench, cabinets, etc...)
Okay, knife it is - thanks.

for small holes, cut your holes into some regular shape, like a square
or rectangle. take a scrap of drywall somewhat bigger than what you
need, and in the center of this scrap, score the rectangle you need
from the back side of the drywall. snap it, but leave the front paper
intact all around your patch, so it acts as drywall tape. helps if the
drywall is a little damp. apply this patch by mudding into the hole,
with the flaps of paper acting as your tape. not only do you not have
to monkey with wood backing, the paper lays flatter than tape so it is
quicker than mud and leaves an invisible patch. this is a slick
trick...heard it called the "california patch".
yes, and use a knife to clean up jagged edges.

Next time you cut a hole with a keyhole saw, angle the blade so it's
pointing towards the center of the hole at about a 45 degree angle.
Save the piece and reuse it when you're patching. The angled sides
will keep it from falling into the hole. I use setting type joint
compound, such as Easy Sand by USG, to coat the tapered edges and bed
the joint tape. I try to make the hole smaller than a 8" taping knife,
so my larger knives will cover the patch in one shot.
