If you are truly looking to have once-per-month water changes, I would suggest that you consider adding very little in the way of fertilizers (Tom may have some more to offer here?!?). CO2 is beneficial for almost any tank and would be for yours, even if you are striving for a low-maintenance set-up.
For PC lighting, you could easily set up a very workable system with two of the 35" long 96W PC lights, slightly staggered from each other. An alternative you may wish to consider, is going with a 48" wide two light T5 set-up, utilizing two 54-watt T5 lamps with individual parabolic reflectors... don't be folloed by the fact that this would only be 108 watts of lighting. T5 lamps with the individual parabolic reflectors pack a heckuva wallop. This lighting, combined with CO2 injection and very moderate addition of fertilizers (maybe only 1x per week) is plenty to provide the foundation for a very nice system!
