The car listed above is an LT model.

Could you let me know the firing order for my engine and if you have a diagram to change out the spark plugs and coils that would be very helpful.

Also looking to change out my (4) O2 sensors if you have a diagram of locations and what bank is what, I'd really appreciate it.

Sure, here is the firing order and how to change out the ignition coil and spark plugs on bank 1 and 2. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car:

Thank you! Extremely helpful. My only question is it says firing order 1, 2, 3, 4, 5, 6. Is 1-3 in the back near fire wall? Or in the front part closer to manifold?

Sure, here is the #1-cylinder identification is closest to the firewall

The cylinders are arranged in 2 banks of 3 with a 60-degree included angle. The right bank of cylinders are number 1-3-5 and the left bank of cylinders are 2-4-6, viewed from the flywheel end of the engine. The engine firing order is 1-2-3-4-5-6.
