I have to pack up to move but I'll work on this some more and get back to you.
The things I use the most are:
My small electric driver with a large set of drivers and drill bits including 1/2 bit.
Needle nose pliers
Handle held ratcheting driving handle with a variety of bits
Electrical and Duct tape
A bright comfortable adjustable rechargeable headlight
The other stuff I have used almost all of but not as often
The typical wrench set of socket, open, and box end in metric and English, including the smaller sizes. Drivers torques, hex, standard and Phillips from the very small to standard.
An few extension, and adapters for drive size, but large to small, and small to large.
A jewelers set of drivers in standard, hex, and torque.
A set of security drivers the ones with the holes in the middle and other odd shapes.

Pliers, wire cutters, needle nose, channel locks.
Large drift pins
Small and large crescent wrenches
Reversible Clamp set medium size
A few small c clamps
