Need help on setting up a closet grow

Hey folks ,

I'm looking to start my own grow setup in a little closet that I own which is completely devoid of anything. It's measurements are 83x45x16in. It has removable hanging beams which can support lights (fuqqin' awesome coincidence). The closet is located in my room, which is on the second floor of an apartment complex.

The problem is I have no idea what I should purchase. The guides I've seen for closet grows are fairly complicated and beyond my expertise. Does anyone have any suggestions for a cost-efficient setup that will grow a fair number of plants. 

I need helping selecting lights, ventilation, and a growing aparatus... I do not yet understand how the compatibility between these things work. Also, will smell be a problem? It's okay if my room gets a little danky but I don't want to alert my whole apartment complex.
 
Unfortunately, I can't make any extensive modifications to my closet so I'll need to get some sort of grow tent or apparatus to house the plants.

Cheers
