GRow ROom DEsign - Improvements?

After a lot of research, I trashed my plans to grow with LEDs and decided on MH/HPS. There are still a few things that have eluded me in my quest for knowledge.
THis is my plan.. 4x4x6.5 ft grow tent with a 1000w MH/HPS convertable ballast for vegging with MH and flowering with HPS. I'm a little confused when it comes to reflectors and cooling. I know I can rig a good exhaust (shouldn't be hard, the tent comes with holes), but I'm unaware how much air should be used to cool the light. My grow friend mentioned how important it is to blow carbon filtered air through the reflector to keep the bulb from exploding...?!?!?!.
If I use a reflector, that is not air cooled, and I rig up a GOOD exhaust sucking all the air from the top of the tent into an attic, is that enough to cool the light or do I need to have ventilation AND a fan on the light?
Are aircooled reflectors worth it or necessary?
Any input would be greatly appreciated.

Yea thats the one. 4x4x7. I hope I win that...I bid on an inline aircooled fan. I don't know much about where the air is moving or if the aircooling even doubles as exhaust but my main concern is can an aircooled inline light be set up in a 4x4 space??? I already bid on the lights and stuff, the dimensions of the reflector are 18x15x7.5 in. To rig up the cooling looks like it takes more space than I have, does anyone know for sure? Also, if it doubles as exhaust too, that would be great...

So if I'm running a 1000w in a 4x4x7 tent, is a 6in vortex fan, (449cfm) and a small oscillating fan, just for a breeze,good enough passive intake? How about with a carbon filter?

I was kind of thinkin for overkill. I figured it would keep everything way cool and ventilated. How bout if i put the fan on a timer? maybe every other 5mins or something? Has that ever been done before or is it better to keep it on?

These are my final plans. My only concern is the position of the carbon filter and the length of ducting used. There is also going to be an oscillating fan not shown in the pic.1) Will the 449cfm Vortex fan work well enough for passive ventilation and light cooling despite the sharp bends in the duct and its length into the attic? I want to place the fan in the attic to reduce noise, my room is next to the front door. Should it be inside the tent?2) Noise reduction ideas? I was going to stuff foam or something into my windows but was wondering if anyone had any tips to muffle noise without sealing the room and probably making it real hot.3) Is the carbon filter ok there, over the light?

So what if the air goes from the LIGHT---->(ATTIC) CARBON FILTER----> FAN? ? The tent has holes in it for air intake on the bottom, I was gonna leave them open.

Oh yea...maybe a small carbon filter can be attached to the fan and made to fit inside the ducting. How farfetched is this idea? I was wondering also, would active ventilation make enough of a breeze for the plants inside?

Hahaha. yeaaa.... INsAnE YielDS. Thanks. If I were to add another fan to the grow tent, besides the 6in vortex rigged to the light, would it wiser to use an oscillating fan on the plants OR a squirrel cage fan or computer fan for an active ventilation? In other words, which one would be the better bang for the buck? I wanna run two fans max for this tent, but I don't know which option is more effective.
