First, please do call Leisure Line. They will be best able to help you get your particular setup going.
Otherwise here's my take on some things:
What if I installed the two 10 amp fuses in the bonnet limit and power vent limit fuse holders and plug nothing into the bonnet limit and power vent plugs? I would use the current 3 pronged female plug from the fume switch to plug into the main module power supply thus if the fume switch is triggered it shuts power down to the module and all will still shut down if the tempure is exceeded?
You can definitely do this. This is how one would wire in a Basic or Basic+ Coal-Trol Digital system into a power vent fume switch, it's just as valid for a Standard/Standard+ or OEM unit.
The other problem with hooking up the fume switch to power the Coal-trol is that you will lose the programming and have to start over on the set up (if the power stays off long enough), though you would have the values for max and min feed so it would be easier.
The unit will remember all of your setup options with the exception of the current time and day. Min, Max, Triburn, HLF, etc. are all remembered no matter how long the power is removed.
The Coal-trol does not control the Power vent in any way and I would definately hook it up to a seperate AC outlet. You want the blower to run non stop no matter what.
Talk to Jerry or your dealer about this point. There are different schools of thought on this. Consider that a power vent pulling air when the rest of the stove is unpowered will still create a negative pressure in the stove (even with a baro damper) and can potentially lead to a hopper fire.
