Doing it right this time

So I have done a few CFL closet grows in the past with less that spectacular results. This time around I would like to do it right. I am getting my supplies list together and planning out my closets, and I have a few questions.

Here's a run down on the setup so you can get some context for the questions.

We are running two closets, 1 veg, and 1 flower. 3plants in each. The flowering closet is in an awkward location in my room, so I am going to have to exhaust into the room(which is why I will be using a carbon scrubber) So that also kind of limits the amount of intakes and exhausts I can have. (Trying to keep it down to one intake and one exhaust.)

Flowering closet
2'X3'
400w hps with vented hood
x3 200cfm inline duct fans. (1 intake, 1 pushing air over the bulb, 1 exhaust going through a carbon filter)

Veg closet
2'X3' (ceiling is only about 4 feet high though)
x3 125w cool white cfl (the big twisted kind)
Passive intake
X1 200cfm inline duct fan for exhaust

1.) for the flowering closet do I need a separate intake to cool the light? I was planning on just blowing air from inside the closet over the light and then running ducting from the other side of the light out through the carbon filter.
2.) do I need a separate exhaust for the light? was planning on only having one.
3.) will the 200cfm fan be powerful enough to go through the carbon filter? I have read that you need stronger fans to push through those.
4.) for the veg closet, would it be better to grab a MH bulb or two that you can put in a regular dome fixture? not sure if these bulbs are the same. (i do not have money in my budget for another ballast)

Thanks in advance!

it's only a 400w light. and it will only be on 12 hours. do you really think it needs seperate in/out? trying to minimize the amount of ducting that will be in my room. And I can't exhaust up, there is another floor above me.

You don't have to exhaust up but exhaust from the top of the room hot air rises you may be ok with just a passive intake and an exhaust fan just keep the run the intake is coming from cool
