As far as the turbine housings, the best option is multiple stages: having them not only ceramic barrier coated, but in turn run the ceramic fabric blankets over them, and then put sheetmetal heat shields over that (like the Banks kit.)
You can do much the same things with the headers and downpipes-- ceramic barrier coating, then wrap them, then use sheetmetal heat shields as needed between the exhaust and any heat sensitive components.
There's a lot of hot plumbing under the hood with any turbo application, elevated underhood temps are the norm. Anything to keep air moving/circulating under the hood is a good idea. Hood vents (like the Mule) are a good option, as are vents at the back of the fenders (Vettes.) Another option is to remove the hood-to-cowl seals to allow the hot air to escape there, or to raise the back of the hood up an inch or so (it works, but sure doesn't look good...)
