First Time Grower with a Little Knowledge Check this out!

So after all the reading, gaining information, I finally decided to order some things(ironically pricey too) to get my grow started:

1. Grow tent 2'8x2'8x5'3

LIGHTING
2. 400Watt HPS (Going to be used for flowering)
- Cool-Tube w/reflector
-Pulleys for adjusting the light
- Dual Outlet Digital Timer
3. 6 26watt CFL 6500k Twist(Going to be used for seedlings+clones.

NUTES
-Grow Big
-Big Bloom
-Tiger Bloom
-SOIL SECRETS EARTH ADDITIVES - EARTH AMBROSIA AND NECTAR COMBO..GOOD CHOICE??

VENTILATION
-Right Now I have no Ventilation, and ALL this stuff is getting shipped to my house.. I cant wait!

Couple of questions though
1. For ventilation I was going to get an inline fan 170cfm exhausting the hot air through the ducts, connected to my cool-tube. Then have another duct w/passive intake

2. I Bought some Scotts Soil .07-.01-.03..Nitrogen is the highest so it must be ok??

3. How Does everything look so far? Lights? Nutes? Vents? SPace? Ideas?
