New to DWC. Need some info

Actually I'm new to hydro all together. but think i am going to do a dwc system. there is a hydroponics store close by but they are expensive to buy stuff i can go to Lowe's or home depot for. but http://www.atlantishydroponics.com/Hydroponic-Deep-Water-Culture-Systems/Viagrow-Black-Bucket-Deep-Water-Bubbler-System-4-pack.asp thats the one I'm looking to DIY. The room is 3'9" x 4'7"x 8' tall. I do have a few questions before i go out and buy the supplies to get started.

1. What kind of medium? Hydroton or Via Stone. I will also get some starter cubes/plugs
2. will this light work http://www.atlantishydroponics.com/Complete-MH-and-HPS-Lighting-Systems/ViaVolt-400-Watt-Economy-Electronic-Grow-Light-System.asp also Atlantis Hydroponics Smart Sun, 6" Air Cooled reflector. Should I go with 400 watt or 600 watt for 4 plants to start.
The reason I thought this was a good light setup is because
Fast start-up - they reach full brightness quickly
Completely silent (big plus)
Small compact design
Produce less heat than traditional magnetic ballasts (another plus)
Fully interchangeable bulb capacity, ballast can light both HPS and MH bulbs..dont know much about mh bulbs. but i always heard you can do it all with HPS from start to finish.
3. I have some nutrients but not sure if they will work or not. http://www.formulaflora.com/product.php?productid=17530&cat=252&page=1 I have the start all in one pack. There is a feeding schedule on the site. Should I follow this http://www.formulaflora.com/pages.php?pageid=13 or no?
I think that is all for now. I'm sure I will think of more questions later. The cooling setup is common sense in my book. Cool fresh air in, hot bad air out. I can get air pump and stuff at the hydro store. but just want to check and see how my list of supplies is coming along. I will go to the store tomorrow or Saturday to get the supplies if yall think it will be OK.

Thank you,

Yeah ive never heard a truer word lol, im still get things a year on' but i think when we all see or hear about something thats giving someone a bigger harvest or they've had no probs we go and get it, well i know i do' im always trying to better my learning and understanding of what im doing and where i go with my grow, plus where ive go wrong.
From the list you've put up i can see that you've done abit of reading up on things so you'll be ok but you can always put a question up on the forum and someone will help you out, peace dude scunk

that's just on my starting list. I've got more planned. just got to find the time between work. off all weekend so I want to get things set up. painted the room today.

if defo aircooled use 600w ! most efficient light out there.
just get growin. you sound like you have done the research the rest is on the job learning.
i love the thought of new people growin it warms my heart !!!!!!!!

not aircooled right now. but need it soon. have a few floros on the plants right now. i planted them this morning after they germinated. after about a week or so ill turn the hps on. i should have my inlines by then.
