First time growing

I'm looking at this grow box- http://cgi.ebay.com/ws/eBayISAPI.dl...akeTrack=true&ssPageName=VIP:watchlink:top:en

and then probably gonna use feminized northern lights or lowrider seeds

so is this all i need to start and some good soil/food?

also, once i put the germinated seeds in the pot, how do i keep them from not stretching and hitting the light itself, i read somewhere that it can start a fire

thanks
