Aside, from removing the drain plug from the bottom of the radiator, I read in the manual that I am suppose to unscrew something near the thermostat. Is this really necessary?

1 - Yes it's really necessary to drain as much as possible.
2 - Yes it's really necessary to remove all the air from the system.

 

I found the name of what I'm looking for. Its the Radiator Bleeder Bolt. Where would that be located? Underneath or by the T-Stat? Basically the manual is telling me to just "loosen" it so that the radiator "burbs".

 

I think you should be looking for both things. Not only that, but have the heater temperature dial set all the way to hot.

On the back of the block (probabaly to the left of the oil filter), is a large flanged bolt that will drain coolant from the block. If you don't drain there, you'll leave a bunch of coolant still in the engine. Watch out, it'll splash all over. Especially since you have to crawl underneath to get it loose.

Then there's a bleeder screw on the thermostat housing. It looks like a brake bleeder, a little nipple with a hole thru it. Open it 1/2 turn or so. When you fill the radiator, air will come out of there. Close it when liquid comes out. Run the engine with the radiator cap off. Open the bleeder screw again in case there's more air collected there. You need to get rid of all air from the cooling system.
