What else would I need to buy besides the vortex itself?

I'm such a newb when it comes to this

is there a guide you can point me towards?
I fail at using the search (dunno what to type in)

Do I buy the carbon filter that is 4inches?Can Filter 2600 4" -
Do I need to buy 4" Metallic Vent Ducting - 25' -

Also I should probably get cooling for my HPS hood yes? Does that need a separate fan of itself?
