Sorry to hear about the crabs Hope those plants get better soon! For C02, I think that C02 injection is a great investment to any planted tank and since I have had experience not using any C02 and a pressurized C02 system on my planted tank, I can say that it has a tremendous effect on the growth of plants and overall keeps the tank looking more healthy. But, you can easily have a beautiful tank like Rivercats who doesn't even have C02 and still has the great results with using glut and the right ferts.
I have always just used ferts and I've gone through many planted tanks, but once everything in my tank is back to normal I want to completely fill it and I'm thinking CO2 might help when I fill in with moss and grass in the foreground. I miss my crabs, I'm gonna get more today my tank is finally in spec this time I'm gonna put a cover of some kind over their pedestal so they can't climb down the air pump hoses lol
