Cooling System Questions

I just dropped off the Radiator at the shop for boiling and a little repair. In the meantime I want to address a couple of things.

First: What's the best way to flush the block?

Second: The Temp gauge isn't working. Is there a way to test wether it's the sending unit or the gauge itself? If it needs replacing, anybody have a part number?

Third: When refilling the coolant, is the old 50/50 mix still the best? Any preference on brands? What about that orange stuff that's supposed to last 100,000 miles?
