For Crypts and Anubias and other low light plants either will work. Personally I would go with the 96w one though. Not only will it give you a little more light in case there is another species with higher light requirements that you decide to keep in the future, but it is also only one bulb. Less to worry about and less to replace.
Just about any tank will see a growth increase if you add CO2. But the species you have chosen would be at the low end of showing improvement. At 2wpg, even with Crypts and Anubias and whatnot I would say it is almost a necessity. And absent of another carbon source, vals will extract what they need from the carbonate hardness of the water potentially dropping your pH. Now that I have added CO2 and seen the difference I will never go back.
