Wheel building - from scratch

I busted a rim recently and will need to replace it soon.. the hub I have is 28 holes which seems to be an awkward size. I'm thinking of going for a pair of black Formula hubs and a black Velocity Deep V, I'll do the front when I have more cash...

I found this on Sheldon Brown...

You will need a small flat-bladed screwdriver, a spoke wrench (I use a DT spoke wrench, but most people aren't ready for a $50 spoke wrench. My favorite inexpensive spoke wrench is a plastic one with a metal bit, called a "Spokey"), a truing stand and a dish stick

In addition, it is helpful to have a spoke tensiometer and an electric screwdriver with an appropriate bit. (My preferred bit is a worn-out Phillips bit, on which I have ground off two of the four fins. This leaves a pointed flat blade. The point pokes into the hole in the middle of the nipple, and helps keep the driver from sliding off.)

Do you really need all these tools? I have a screwdriver and it sounds like the 'spokey' would be cheap, but the rest??

I fancy having a go because I like fixin' shit, and would like to be able to do this when it (inevitably) happens again. Any advice or opinions about choice of parts appreciated...
