As an electrical engineer, I'm not sure what you mean by a voltage relay. Radio Shack does sell all of the electrical stuff that you say you can't find. But frankly, by the time you gather all the items you need, you'll find that you've spent a lot more money than you'd planned.
Oh, and don't use a soldering gun for delicate PCB and IC work. It's like using a howitzer to do some squirrel hunting. Use a soldering iron, instead. And no, they ain't the same thing.
