That is the same I use - an el cheapo small drill press with visible runout (not much, but visible) on spindle at 3200 RPM. I switched to carbide bits and they are SO MUCH better than the HSS bits. The carbide bits don't "walk" during drilling "as bad" as did the HSS.
I like BIG pads - without a solder mask to help hold the copper in place, it's easy for them to lift during rework. My usual pad size is as large as possible - on .010" pin spacing sometimes have a very small space between next pin. ON DIP sockets I will use a longer pad to have more copper left on board and still have room to run a trace between pads.
