They. Are. Amazing. SUCH clear and loud sound.

1: If I decide to put the subs under the mains towards the side of the stage, close to the walls, would that give the wall boundary re-enforcement you're talking about?

Yes. Provided the radiating plane of the cabinet is less than 2.5ft from the boundary, the reinforcement will happen. In practical terms, this means that the cabinets should likely be FACING the wall.

As a starting point, I put direct radiators 1/2 the cone size from the wall - so a 15" sub has a 7.5" gap from the wall, and an 18" sub would have a 9" gap from the wall. Add another 6" every time the number of cabinets in the pile doubles.

If you have more than eight cabinets...you should already know what you need to do.

2: If I put the subs in front of the DJ booth, and have a panel behind them,would that count as a wall? How thick would that panel have to be to work? (If it works at all?)

A boundary must be one wavelength in all directions, and should be "rigid" (anything "interior wall" or better is OK). At 40Hz, a wavelength is 28ft. So, provided the panel is 28ft in all directions, it will still work. In practical terms, you really want a solid wall.

Keep the doors on the wall with the sub closed whenever possible. A single open door will make a small enough difference to ignore. Four sets of double doors that are full open (e.g. like a typical gym) will have a substantially noticable effect.

3: If I have the option to, would it be better to rent out 4 1000 watt subs and group them together towards the center?

Sound level is not measured in watts. Sound is measured in SPL in units of dB, and the response will vary across the passband. Without an SPL chart, or at least a "@1w@1m" sensitivity rating, it is difficult (or impossible) to compare the performance of two subs based only on peak power handling.

Given what you are doing, either set of subs would be OK. Pick based on cost, or pack space, or weight.

You will only be able to do the best you can with the sound being its in an open gym. If you have the time try different set ups to hear what sounds the best.

Lighting is also included towards the bottom of the google doc. Would you say that setup is alright? (The lighting board gives full control over a total of 8 LED lights)

Opps I must have missed that, If you think they will be enough then your good to go.
