Hi Ray and welcome. My setup is very similar to what you describe. My second saw is off to the left of my main saw and the jointer is behind me when I'm at the main saw. Quite often I have both running at once so that I can make a cut and then clean it up on the jointer before making another cut. I have about a 4ft long outfeed table on the main saw but a cupboard the same height would work too it's just that you need to extend the mitre grooves across the top of it for a ways, especially if you use a sled and I highly recommend you make one.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
