I know that Cottington Woods tends to have traps, since their GM is an old school trap-rogue.
For lockpicks, take a look around on the side of the road for broken off street cleaner bristles. They're thin, slender, and made of spring steel. A little work with a dremel and you can make your own set rather easily. Not that I've done it myself or anything...
Another sneaky useful tool is something called a "spark gap tool". It's a little folded widget that has a stack of metal sheets of varying thicknesses. It's really meant for measuring the gaps on spark plugs, but the applications of a near paper thin peice of metal when disarming a trapped box cannot be understated.
That being said, having something like an old credit card is good too, because it's [i]non[/i]conductive. Last thing you want to do is bridge those two contacts with your probe and hear the dreaded buzzer of doom.
