Trumpy - just reviewing your list - seems like a good start. Here's my $.02
Linesmans Pliers (get the Klien or Ideal with the fish tape puller slot in the back of the head)
Diagonal Cutters (get the Klien 2000 series - they're hardened to cut nails and such - if you only use 'em on Cu, they'll last forever!)
Long Nosed Pliers
A decent set of screwdrivers, if Insulated, all the better. (Or a good quality 10-in-one set, with extra tips, like the below mentioned #2 square drive)
A 10" Crescent
An 8 metre Measuring tape
A Wall-board saw (get a good one, not the cheap-o wood handled version, unless you're into sharpening blades)
Automatic Wirestrippers
An Electricians Knife (or a good utility knife and sheath - buy a brand name - stay away from the plastic $.99 specials, and avoid the cheap "made in Taiwan" blades)
A Square Drive (Robertson No.2) Screwdriver.
Some type of Solenoid Voltage Presence Indicator. (get the one that has the continuity tester integrated. Saves time tracing lines during installs)
Additional items-
Fish tape? Maybe only a 50' to start.
A pair of (8"? 10"? Whatever the "middle" size is) channel-locks - I've got the ones that resemble the Knipex Cobra head - there's a notch in the jaws to grip pipe more effectively.
A Klein or Ideal conduit fitting / conduit reamer equipped screwdriver (for those of us running stick). Also handy if you're using a hacksaw, instead of pipe cutter.
Auto-strips are nice... when they work. (My dad never could get his Ideal one adjusted correctly) I've gotten more use out of the Klein "all-purpose" wire tool (the little one) that strips 10-22 awg, has cutters, crimpers & pliers, and can cut/clean threads on 6-32, 8-32, 10-32, and 10-24 screws. On the other hand, my foreman swears by the Ideal T-series, and our boss still uses dikes (Diagonal cutters). Personal choice, I guess.
I second SvenNYC's call for a non-contact voltage detector. Saved me from more than a few "energizing" moments...
Carpenter's pencils, a medium point permanent marker, and a lumber crayon. Nothing like making a mark during a rough-in to confirm what (and where) your journeyman told you to install.
(as mentioned in another post) (Good quality) kneepads, leather gloves, safety glasses, and a hardhat.
