I could use some information on wiring the high and low limit water switches, and also the wiring to the blower and auger.

the control on the back is the first photo and is set at 200 degrees so I believe it is the high temp control. the second control , the second is set at 120 degrees so it looks like the low temp control, what do you think of this set up?

Those should work fine. Use the first one for the high limit and use the other to maintain the boiler temperature. Bring the timer circuit in prior to the high limit control.
