What direction should I go?

I have thought about it. But I kind of want to get rid of all the DoD parts first and it seems easier to start from the top and work myself down that way over time unless I am mistaken. The way I understood it was the DoD lifters and all that need to be out before any big mods like that

I was just looking at bang for the buck. Just have to figure in money for head bolts/ gaskets on top of the price for a normal ls motor cam swap. You could probably do the whole swap for under 1k and pick up 50 hp. Just my opinion. The new manifolds on most gm cars seem to be pretty efficient, so you don't pivk up a HUGE amount. If you are willing to spend the extra time it will be very very worth it.

Intake upgrade would be nice if you're up for the project. Ported throttle body and a MAF upgrade are smaller easy upgrades, I can help on the MAF upgrade.
OBX LS4 headers can be had for $475 shipped from the place I got my OBX headers from for my TrailSS. I'd at least upgrade your downpipe using a ZZP 3" unit, again a smaller easier upgrade, easy install.
Nothing wrong with the 7th gen brakes but if you want to upgrade to 12.7"s I'd pull some low mileage calipers off ebay/wreckers from a 2006+ Cadillac DTS, same rotor size as GXP, similar pad size, and you'll find em for $50 a side or less. 2006+ DTS (not limo, the regular DTS), 06+ Lucerne with Northstar, 08-09 Buick Super, 12-13 Impala police and 07 CTS Sport.
When the time comes for a cam, have the intake and headers already done or do em at the same time. The G8 guys are shoving in LS3 camshafts to replace their DoD cams with very reasonable results. Cam costs $130 brand new, $60 for some LS6/3 valve springs, plus gaskets, hard to beat, especially if you're handy enough to install the cam yourself.

With the brakes I need to make sure I get the brackets with them correct?
We will see if I make it to a cam. I would love to but like I said at this point it seems like the last piece in the puzzle and have plenty of work to do before then
Thanks for all the good info Will

No complaints yet on the OBX headers I run on my TrailSS. Good fit, good performance. Not sure who they copied on those, they obviously copied the DT headers on the LS4. I wouldn't have concerns buying them for as inexpensive as they are.
And yes ensure you get the brackets with the calipers!

Off the top of my head:
The 05-06 is the 1x cam signal and 3 bolt
The 07-09 is the 4x cam signal and single bolt.
I forget now if they make a 1x single bolt cam gear, is that why you asked? LS3 cam is single bolt.
