I need help on if I should do anything with my transmission/torque converter or just leave it as it is. It's a C6 by the way.

Looks like the cam matches the intake. Your gears are 3.50 to 1. Have you tried it yet? You are in the ballpark on everything. I would not worry about the torque converter yet. High stall converters create a lot of heat in the tranny.
If you find you are bogging down in the mud, you might have to change your gears to 4.10's.
