New setup...advice, please.

Switching to a new grow setup. Please give me your advice. Greatly appreciated!

I am looking to run the Secret Jardin DR 80. (2'8 x 2'8 x 5'3 ) in my walk-in closet

1.) Can I run my 600w Adjust-A-Wing from GC Hydro or do I need a 400W?

2.) The guy at the local hydro store told me I could run my tent setup with my wak-in closet door closed if I do the following:

-run a co2 setup
-have an inline exhaust with can filter to remove odor (I have 449 cdm Vortex PowerFan exhaust)\
-Run a portable A/C (the temp gets too high in the closet)

I was going to put (9) 8.5" pots in the tent

what about this instead of a portable A/C system?

THOUGHTS? SUGGESTIONS?
