Hmm.....look at bathroom vent fans for that size. Cheap for you and will do the job you need......Cooltube for the light will work for you too.....As far as any cooling needs. That will come from the outside the area in cool air in. AC the room it draws from if need be....
Odor,,,,,I don't, at my size,,, I can't......For you, any air pulled from the area will smell (duh). I might add a small activated charcoal filter if smell would be a problem. You will have to figure room size to fan size to filter size for your needs. My guess is you need to move 170cf a minute. Now you have to find a fan and a filter that will fit that need, I don't know that one off hand as fer if the bathroom fan would push that actually
through a filter so.....These guys will help, call them, They are straight up quality people, who grow like we do.

Aw hell, I looked for you....Looks like the Can 33 combo is what you'll need to kill the smell.

Ask me in a year on how to reactivate the carbon in the filter so you don't have to keep buying them!
