I just noticed I never answered yer question, I'm sorry I missed it so here tis:
I just put two bricks laid on the bottom on each side a the chip rack. Nothin fancy, cheapest ones I could get. They work real well.
I use water in my foil lined pan, I thin it heps keep the humidity up in the box an may hep keep the meat from loosen some a it's moisture. I use it fer that more then a heat sink. Sand would work fine fer heat sink though.
I have never needed the needle valve, so can't say how it works, would think it would, but like you, don't wan't ta take a chance on er goin out. I thin the stack might hep draw a bit more air through the rig. That's a good size hole down there where the burner is.
