Is lighting related to the need to inject co2? If so I have 3.6 watts per gallon on a ten gallon planted tank, do I need to inject co2?
Is lighting related to the need for co2?

No it is not, however once you get to a certain point the lighting will not make a difference and no matter how bright it is the plants will not grow any faster. In other words, once lighting reaches a certain point it will have no effect unless you inject Co2. I do not know if Co2 is necessary for such a small tank.
True but! The more light without Co2 is a recipe for a serious algae breakout.
As for the Op, lighting is different for small tanks for instance I have a 27watt Home depot Cfl over my 5.5 and I can really only grow low to mid plants no carpets...
Nanos don't hold the standard WPG rule I believe.
If you don't plan on adding Co2 just cut the photo period and use Excel if you feel the need.

like mott said, the general wpg rule doesnt really apply to small tanks. If you want, you could use a liquid co2 (seachem flourish excel).
I would consider 36w over a 10 gallon to be medium lighting. No need for pressurized CO2 but I would highly suggest adding some form of carbon.
Vals for one. I'm not sure of what others, except that subwassertang always dies within a week or two on my 2.5g that I dose with Excel, but it is doing just fine in my 20g and 75g that I do nothing with (other than WCs and fish stuff of course).
WPG is not necessarily accurate to begin with but can be used as a general rule of thmb to describe lighting....
WPG becomes extremly inaccurate when you start talking about small tanks or very large tanks.
Excel may harm vals, anarchis some mosses and some ferns, you can google it to find the info.
The point at which you need co2 is a fine line IMHO. i run 2.5wpg on my tnak and if i need it kind of depends on the day...but i like it but i can also run 5WPG and i defiately need it.
generally...
more light = faster growth
faster growth = faster co2 uptake
faster growth + faster co2 uptake = faster nutrient uptake
faster nutrient uptake, growth, co2 uptake = more light
as you add more of one thing you need to consider the other important pieces of the puzzle.
