The only one I saw did.
>2. Is a supplemental vacuum pump advisable to reduce the amount of time

At a glance it seems like a good idea. You would need a one way check valve
on the output side of the vacuum pump.
>3. What is the compressor capacity (cubic feet per minute or other

>I think my compressor could be smaller than those currently used.
Don't have a clue.
