On the air fresheners, if you were thinking of using the type that sprays chemical into the air (which are the most effective), I have to advise to not put them on the inside of the grow box. The chemical will get on the leaves and the worst outcome is that it could kill the plants. A probable outcome is that it would reduce yield and reduce potency. A definate outcome is that your smoke will taste like crap. As far as your lights go, they will need to much power to use batteries. I use cfls and have a series of small lamps. If you have room, that would be your best option. If you don't have room for lamps and your handy at building stuff, you might consider going somewhere such as Ace Hardware and purchasing some light sockets, attaching them to a small piece of wood or something, and wiring them to power cords. I am no electrician so I can't really help much on this but BE CAREFUL! Electricity is a real bitch if you don't respect it.
If you decide to order seeds.... I noticed another poster suggesting AK-47 and I definately don't mean to contradict him as I love the choice (it is a small, fast growing, very potent strain), but it is also among the strongest smelling plants while being grown. If you search around at the seed stores you can find some strains that have low odor while growing and it sounds like that might be better for you.
-Peace and good luck to you
