Step 1 – Open hood and pop off plastic engine cover
That behemoth of a top cover on your Vortec V8 is held on by only two tabs. Gently lift the front until it pops up from its post, then reach under and toward the rear of the cover to pop the back tab. (It's so easy, a US Congressman could do it!)
Step 3 – Remove air intake tubing
At each end of the intake tubing, you'll see a worm-drive clamp. Loosen both clamps at the air cleaner and TB unit. There will also be a tab at the far left side rear. Simply pop that off. Finally, unplug the sensor plug on the intake tube.
Step 4 – Remove power leads to the throttle body
Simply push down on the gray clip tab, and remove the entire plug. You should not have to remove the pink clip.
Step 5 – Remove the throttle body assembly
Using a 10mm wrench, remove the two nuts and two bolts. Then, slide the TB off the studs.
Step 6 – Inspect O-ring and replace if needed
The O-ring should be intact; however, if it has any cuts, abrasions, or is just plain grungy, you should have a new gasket in the new throttle body kit.
Step 7 – Install the new (or refurbished) throttle body
Simply line up the stud screws and slide the unit in place. Tighten the nuts and lower bolts in a crisscross pattern until tight. Do not over tighten! There is no torque spec for these, so use common sense when tightening. Plug the sensor plug in, and secure it with the gray clip.
Step 8 – Reinstall air intake assembly and cover
Install the plastic air intake tubing assembly, tighten the worm-drive clamps, and push the PCV valve back in place. Simply line up the front and rear tabs on the engine cover. Then, push down firmly until it snaps into place. Plug in the sensor at the air cleaner end of the intake.

So I've been reading around on upgrading to the LS7 throttle body (Part# 12605109) but had a few questions. It seems that most people notice improved throttle response but I have also read that some people experience higher idle RPM's and that their fuel mileage went down.

MAF calibration is "hard-coded" in your ECM table, and doesn't "self adjust". The MAF is a mass flow sensor, and is calibrated to air flow rates within the stock intake. Changing the throttle body should have zero impact on the MAF accuracy, since you're not changing the MAF tubing size or location.
