I'll second the recomendation for the Roadrunner wiring pen. It's very useful for one-off projects like this.

As for drilling holes for an IC socket in copperclad board, I used an odd bit of stripboard as a drilling jig.

At one time you could get a tool that consisted of a drill bit with a cylindrical cutter round it. It drilled the hole and then cut away the copper leaving a nice circular pad round the hole. No idea where you'd get one now.
