That's a pretty good list based on a quick review. My only contribution at this point is to recommend that you get all of this done sooner than later. With that many parts changes/etc. you want to be able to drive it around for a while before the long trip so that any issues will be discovered locally and not on the long trip. You also need to have time to order more parts, change things after you are done, etc. which often can be needed. I'd want to be done with all of the important items by mid November personally since the Holiday's get a bit busy and I assume you hit the road some time in December. My goal would be to knock it all out by the end of October to pad things and have November for the testing/fine-tuning.
