Looks about right to me but I'm just learning about turbos and all so I wouldn't hold alot of faith in my comment.

If I understand your diagram correctly -and I'm not sure I do- you're venting manifold pressure to the engine compartment?

It seems to me that you'd want the boost controller to replace that distribution block thingie just to the left of the turbo inlet. 
Inlet hose > controller > wastegate

Someone else may have better info regarding your year model.

Thats how I learned it worked but like I said I'm new to this.

What you diagrammed won't work.

Disconnect your wastegate actuator and loop back or plug off the line you remove.

Connect inlet port of the boost control valve to the vacuum tree. Connect the outlet to the wastegate actuator.

Start off with the boost valve screwed out and ease in a little at a time so you don't overboost your setup.

Look at the video on this page.

Sure, but use proper vacuum line. The signal may be slowed a tad over that long of a run, but it should work fine I'd guess.

I just want to elaborate my last statement after finding this in the Megamanual (Megasquirt)
 qoute:
Don't worry about how long your MAP sensor vacuum hose is. Intuitively it seems that shorter should be better. However, a few people have done tests to see how bad the effect of a long hose was on vacuum signal propagation. With a ~100 foot (~30 meters) coil of rubber tubing in between the MegaSquirt® and the engine, the result was that no delay was apparent. This was with about a 10 millisecond resolution clock. The reason for this is that air has so little inertia that it moves very quickly in response to a vacuum (this is how we fill the cylinders, after all!).

So, run the lines wherever you want!
