Pedro has good directions on how to use it here: Flush Coolant System

Or you can follow the instructions that came with the tool.

Replacing the water pump is your call. It might last another few years, or it might fail tomorrow, as could the new one you buy. I changed mine (MY99, 78K) because of all the dire doom and gloom warnings. I found the old one I removed was in perfect condition and did not need to be replaced, but I guess that's better than waiting for it to fail. I dunno. I tend to think there have been a lot of perfectly good water pumps replaced and thrown out because of a few documented failures. Just like IMS bearings.

If you're going to replace the water pump, might as well do the thermostat. I wouldn't bother with the coolant tank until it actually fails.
That is not correct, we use the Uview regularly to get the air out of systems that had a customer’s DIY cooling project go bad and leave air entrapped in the system. As the Uview never actually touches the fluid level in the surge tank, it cannot suck out the coolant, but will pull out any air in the system.
