are you talking about hooking up the out of one to the in of the other? What would be the point of that? The pump can only flow so much and you would be limited by the hoses, the ball valves and the first pump anyways.

That would be in series. On my dual head pump, i got 1/2" split into 2 3/8" to go to each side of the heads and then the output back into 1/2" to maximize flow. Series and parralel are two opposite things.
Pumps In parrelel
Got it. Now he question would be would the pick-up tube and ball valve be able to feed the two pumps? If not then no gains.
For similar centrifugal pumps with similar plumbing, whether in series or parallel, no matter the size of the the input and output, there would be flow gains (as long as the head height is below the max head of a single pump). Maximizing the flow gains is a different matter.
Pumps in series can yield a higher pressure, and pumps in parallel can yield higher flows. If you don't need pressure (low head height), the parallel pumps will give more flow. If you need pressure, the series pumps will provide more flow. Picking which setup to use is system dependent based on comparing head height vs. flow- as head height increases, the flow rate for the pumps in parallel flow rate will decrease below the flow rate for the pumps in series.
The input/output restrictions are a separate but related issue. Basic principles of decreasing flow restriction on the input and output apply to both series and parallel, but are more critical on for parallel. To maximize the parallel setup, the outputs should remain separate until termination or be combined into a larger pipe. The effect of increasing restrictions in the lines is similar to increasing head height.

What are the valves at the top of middle pot and middle of the right pot for? I'm guessing the one at the top is for sparging, but I can't guess what the other one is for.
Anywho, I think I just got motivation to hit the local scrap yard!

The valve in the middle of the boil kettle is to recirculate back into the kettle after running through the counterflow chiller. It is a 3 way ball valve, so once the temp of the wort going back in hits pitching temps, I turn the valve and start going to the fermentors.
That is so awesome. My dad got some cool things from the local dump/scrap place when they allowed you to pick through it, like a stainless steel sap pan (for maple syrup) that my brothers used to make syrup. I wish my habits had me frequenting places like that 
I am also in awe of the price. That's just amazing. I'm so impressed.

I did this same thing again yesterday, only with a stout. I hope it comes out well.
