Off the top of my head, here are a few specific tools/gear that always come in handy for me. Might give you a few BOB ideas.

-Locking pliers (i.e. Vice-grips)
-Groove joint pliers (i.e. Channellocks)
-Adjustable wrenches
-Allen Wrenches
-Folding Ratchets along with:
--Self-sizing sockets (i.e. Gator Grip)
--Ratchet Extensions

Some other odds and ends:

-Hose clamps
-Electrical tape
-Duct tape
-Zip ties
-Super glue
-Epoxy putty
-Scraper blades
-Break-Free CLP Aerosol
-Construction pencils

Safety gear:

-Leather gloves
-Dust Masks
-Safety goggles (Goggles, not glasses. Glasses do nothing for dust.)
-Hard hat
-Bright colored flagging tape


On a side note, a lot of the items you listed could be taken care of with a single multi-tool or swiss army knife. (can opener, toothpick, tweezers, nail clippers, ect.)
