I have been super happy with my Ingersol Rand 2112 3/8 impact. 280 ft/lbs
Grinders: more = better, I would rather have 3 ok ones, than 1 great one, the time spent changing out implements gets old fast. Going to need one each : flapwheel, cutoff wheel, wire wheel. The hitachi brand ones at costco are a bargain at $30 each, much better than HF.
Sharpies, chalk line, speed square, angle finder, protractor, and a good tape.
Micrometer - get one that does fractions, no more searching for that pesky chart.
A good set of drill bits - I find the Dewalt pilot point tips to work well for me.
A good 1/2 drill - my milwaukee has handled everything I have ever asked of it
Well that's a start...
