I think light spilling over the sides of your tank is going to be annoying since the light fixture is larger than the length of the tank.
However, the big issue here is the intensity of that light over a 10 gallon. I have 40 watts over a 10 gallon, and CO2 and adequate fertilization are necessary. You don't discuss whether you plan on dosing at all. Without macro and micro fert dosing, I get all kinds of deficiencies due to the high speed growth from the light.
At very least, you're going to need to go with DIY CO2. You can add Excel as well, it doesnt have to be one or the other, plus excel inhibits algae growth. Pressurized is something you can pick up later on, with either a 5lb tank or a paintball setup. But definitely at least start with DIY CO2 when you set up this tank, or algae will be rampant.
Regarding your filter, I'm using an HOB filter (aquaclear) with a coarse aquaclear sponge as the first stage of filtration, then filter floss, then a bag of purigen (i love this stuff), then some ceramic bioballs that came with the filter. It works for me, and I've never had clearer, cleaner water. Of course, I've never had a canister filter either.
