The non-drive side pedal has a left-handed thread which tightens counter-clockwise.
The drive side cup on British/BSC/ISO bottom brackets has a left-handed thread which tightens in the opposite direction. Note that some click-type torque wrenches will not click when tightening counter-clockwise.
Most self-extracting crank bolt covers have a standard right-hand thread so they tend to back-out when used. You should tighten them with the appropriate pin spanner so they don't vibrate loose and fall out on the road.
You want to lubricate the bottom bracket threads. Use anti-seize if any of the parts (threads or bottom bracket cups) are non-ferrous (aluminum or titanium).
The bottom bracket shell should be faced square and 68mm wide.
parktool.com has illustrated guides. youtube.com should have video.
Also does that sound like a okay price for a LBS to replace a crank?
That's the most ludicrous thing I've ever heard. It doesn't take fifteen minutes to remove pedals, remove bottom bracket, install bottom bracket, and re-install pedals.
Also note that you'll only need one $20-$25 bottom bracket tool since the 16 notch tool is the same for all popular external bearing bottom brackets (Campagnolo, FSA, Shimano, SRAM) and most if not all of the uncommon ones.
