I wouldn't worry one bit about what other people on here "think" about your setup. It's "your" setup and I'm sure you built it around how "you" drive the car and what "your" goals are. Who really gives a **** about what joe blow says. He's not the one driving the car or spending your hard earned money on the parts. I'm also sure you worked with Texas Speed on the setup, since the parts are theirs, so it sounds like you've got all your bases covered and will make some great power. All that's left to do is get it all installed and enjoy your new monster. 
Who's tuning the car? That'll make a difference in how well it runs since the MS4 is a max type cam.
Also, the FAST 36lbs should be enough - they'll be closer to 43lbs in your rail.

on everything except the cam if its a street car. In that case the cam choice could be much better.
I just ordered and recieved my 225 heads and ms4 yesturday. I have a 0 milage ls1, 1 7/8s, fast 102, and a 4000 stall. 410s, 3100 lbs I cant wait to get it all back together. Should be a beast. Please post updates. Itd be great to see what numbers your getting with yours
Unless your setup is basically like mine. I designed my setup to be able to run an LSK lobe. And then chose endurance lobes so I wouldn't beat all my expensive valvetrain components to ****.
Looks like the OP plans on running a LSK lobe with the stock rocker arms, heavy stainless steel valves, LS7 lifters and I'll assume pushrods not very suitable as well. Not a good combo for that MS4 cam what-so-ever. And if TSP suckers/convinces him on getting them PRC .675 EHT dual springs "upgrade", it'll even be worse.
