~ You don't need the skimmer. That's for saltwater, which gets protein muck buildup floating on the top... planted tanks don't (that I know of anyway).
~ re: co2 line placement - do you mean the hose line itself or whatever you're using as a diffuser? Putting it in line with your filtration outtake vent like you mention is a good idea, if possible. Put a check valve ($1.49 at any LFS) between the bottle and the tank and no worries about backflow of yeast into the tank.
~ Actinic is for saltwater and the light concentration is way higher (if measureed in Kelvins) than a planted freshwater tank needs, starting above 10,000 and going up from there.
Ideal plant light range in Kelvins is anywhere between 2000 (red-ish) to around 7500 (blue-ish)... 5700 to 6500 is probably easiest and most ideal for the planted tank, but others may want to add their input here.
