That's a pretty good steal on your tank there. High light
- more than 3.0 watts per gallon (wpg) Medium light
- 2.0-3.0 wpg Low Light
- less than 2.0 wpg
Depending if you have pressurized CO2 and ferts, and like to grow plants fast, then go in the High tech range. If you want medium growth go with medium light, but pressurized CO2 and ferts are still necessary but you just have more wiggle room for mistakes. Low light do whatever you want, just pick the appropriate plants.
As far as I know AH is the cheapest place you can get those retrofits and ballast easily. I know some try to go to home depot and find such ballasts but I think it may cost even more, or they don't find the right one. I personally would just fork out the extra $20 and get the AH ballast, and kit if you need it.
