Well, I think the game plan will be to first (after fixing coolant leak and acc. belt/tensioner issue) get a real exhaust on it and see if that helps. If it's still hotter than I feel comfortable with, I'll be pulling the turbo, manifold, and downpipe back out, high-temp coating the exhaust housing and coating+wrapping+coating the manifold and downpipe. I think it will look better than discolored stainless too. Hell, I'll probably coat and wrap everything anyways. The coating is a baked on finish, so I expect it should be pretty durable. (I sell it at work, so I was reading the lables on the DEI coating and wrapping. Discounts FTW! I'll heat cure everything in the oven before installing it, so it should turn out nicely.
As for fixing the leak...

Yes. That's what I did.
I guess it's a little easier for me since my manifolds are cast and don't drop down low like a tubular style. And my engine bay isn't solar flare hot like you described.
I think that if I ziptied the hose connecting the two fittings to the hard piping running to the front of the engine that it should stay out of harm's way. I'll double check my clearances and see if that will work.
And to answer my original question, I guess I shouldn't worry about the manifold cracking from keeping the heat in because I've been searching for info outside of this thread and haven't found any such complaints.
Honestly, I'm expecting the temps to drop a lot once I reduce the backpressure.
