4x55W PCs are usually a good choice for such a tank if you want very
fast growth rate. Otherwise 4-6 32W T8 bubls would also work well.
Depends on what plants you are looking to grow really and how often
you want to prune the tank.

I'm looking for some insight/experience into what lighting system
(watts) I should get for my 75 gal. tank? This will be heavily planted
with CO2 injection and all that good stuff. The tank is the standard
48" x 18".

Any advice would be appreciated!
