Setup Suggestions, input greatly appreciated!

Sounds like you have a decent plan then.

So in the end I'd just make sure you spend the money wisely, which planning ahead like you are doing now will help with.

HD's are great pistons, and are definately "overbuilt" for you as you stated you wanted anyway. But money could be saved by going with those manley's (again I have no experience with them) or other cheaper proven pistons like were menioned (Ross, Mahle, etc). But like I and others said, I'd personaly opt against the standard Wiseco's.

Eagle rods are going to be more then fine for your goals.

272 cams. Im still a fan of the very much proven HKS's. Find a set of good condition used ones and they should be decently priced, and you'll be good for years to come. If you do plan to rev semi high, you may want to consider some better springs just to "help you sleep" as you put it. Stock springs aren't aweful, but if we're talking about a head with 120k miles, those stock springs may not be like new anymore. Some cheap crower springs would be affordable, and would again work for plenty of years to come, as long as you don't go to some more extreme cam setup.

I think you're going to end up with a pretty strong platform that you'll be able to build upon in the future and will withstand a lot of abuse.

One thing not mentioned, that is becomming more important to me, is ensuring you get a good seal on your head/block. Consider L19's and a decent headgasket. Once you go to a larger turbo setup and higher boost levels, you start to run into head lifting issues. If you get a nice good seal from the get go with strong fastners and a good HG, then you hopefully won't have to worry about that ever.
