Don't take my word on compression wise, but if you're going to go SC I would stick with the 10.1:1 pistons you were planing on, however WAIT to buy them becuase buying a used engine for the build up is a good idea, you don't know if the motor will have to be bored out or not.
You're plan sounds pretty good to me, however I'm thinking with forged pistions and Eagle rods, you can go a little bit higher than 8 lbs of boost.
I currently have a 3400 block with the rotaing assembly in it, in my basement. I plan on throwing in a bigger cam and the heads I bought from Matt Fuller a few years ago, (they are already on the car with LS1 yellow springs and 3500 valves and maybe 9.7:1 CR right now. Fuller did suggest a .060 MLS gasket (i think) and my CR should be 9.996:1 and that will max out my cam. He has the next cam up from what I bought and his car is very borderline streetable, according to him. I'm going to be using stock pistons. No need to go forged in my case since I'm not planing on going boost
Of course, I'm gathering parts right now, except for pistions, since IDK if that block will have to be punched out any. At 160,000 miles, I think it will have to be
