With the thermostat out, you can take off the lower hose, radiator side and flush it. Thats probably what I would do myself.

Also there is a drain on the bottom of the radiator on the drivers side.

Are you talking about the hose or the drain?

It is in the bottom of the radiator. It should be a little nipple sticking out. You will need a 13MM socket to loosen it.

If you are flushing it then I would say yes.
If you are just changing the thermostat I would say no. You can change the thermostat and not loose to much of it.
