Also what should i do if the throttle plates are not closed all the way? How should i go about fixing that? Go to a junkyard and measure the distance between the bracket that is for the thottle plates and the throttle body? Or something else? Thanks

You are over thinking this. The blades should be almost closed, a light from behind will just peek through when properly adjusted.

Do you think i could check the VRES by using a air blow gun witha rubber tip and the air regulated down to check for leaks with it off the truck? Or is that a bad idea?

Yes I have, and carb cleaner. I do not trust any of those methods to tell you the truth. I prefer the hand held vacuum pump/gauge method. Propane scares the he** out of me. Carb. cleaner is a lot less volatile to work with.

The vacuum reservoir has a check valve in it. Trying to pressurize it from the manifold port is not supposed to work. You could do it from the "load" side I suppose. Just pull it off and look for signs of rust through. If you suspect anything at that point, pressurize it.

Yes you should cap those if nothing is connected to them now, one should go to canister purge, but if left open they would be a vac leak.

As noted the canister purge valve has it's own port.
I am referring to the port with the hose attached in the upper left in the photo. The corresponding return port is on the lower portion of the throttlebody. Neither are open to atmosphere.

I was betting on the throttle body hot water pipes the OP was referring to.
