I think I have all those part numbers covered, along with the '05 MY shortfalls in the following thread:
Write Up: Bullet-Proofing the 6.0L PSD.
Turbo feed lines were a '03-'04 shortcoming, it looks to me like you have the other '05 fixes already listed in your post. As to the reuse of gaskets, I'm not sure if you'd be ok to reuse them or not. It has always been my practice to use new software.
Here's a question for you, what are you going to do for the coolant system? Continue using the Ford Gold, or make the swap to a good silicate free ELC. Regardless, I recommend doing the flush while your old oil cooler is still in the truck, before you start all this work. Reusing Ford Gold coolant, you only need to flush with the VC-9 (or Restore Plus) and distilled water. If making the switch, you need to do Restore, and then VC-9 (or Restore Plus) and distilled water. Fill the coolant as the last thing.
Either way, I'd also install a Coolant Filter, to get that casing sand out of your system.
