Sorry that I am a little late to the party. Looks like you have a well detailed plan. One thing I should mention is that the GM Performance harness and ECU combo, like I am using, does not support automatic transmissions. It is a manual trans only harness. If you are going with an automatic, I would suggest getting in touch with Speartech. If you want to use the GM harness and explore other options, there are a few good ones. My favorite would be to contact Twist Machine, and get one of their programmable ECUs.
I would go with the stock Corvette accessories. Notch the frame for the A/C compressor. Use Edelbrock adapter plates, as they will mount the bellhousing in exactly the same position as before. Edelbrock also makes nice headers for your application.
I am using an LS7 cam and my combo made 418RWHP. So I would definitely recommend some kind of cam swap. Even a super mild cam will get you an extra 30-40 HP without sounding like it has any kind of non-stock cam.
If you have any specific questions, please do not hesitate to ask.
