Re: Workshop layout

I have a somewhat similar array of stuff as you describe, most of which is in a 12' x 20' building with a 9' x 9' shed attached--so, about the same amount of space as you're talking. It is tight, but workable.
My biggest goals in laying out my shop were to ensure I could get through most projects without having to move the larger machinery around, in particular the saw, jointer and planer (even though the first two are on mobility bases), and having access to work on from four sides of my workbench. Achieving this in a small space is going to impose some pretty clear and immediate constraints, so if these goals appeal to you as well, I suggest this be where you start your planning.
For me, I wanted to able to rip something up to about 8' long, so the saw (meaning the blade) has to sit about halfway between the front and back wall on the long dimension of 20'. I have a small sliding table saw, with a detachable outrigger that I use a lot and so prefer to leave installed most of the time, and a 30 inch rip capacity. I find that around six feet of clear space to the left of the blade is the bare minimum practical, both in terms of being able to cross cut 95% of what I do and having sufficient room to maneuver around the saw and outrigger without being a contortionist.
Similarly, I wanted to be able to easily joint and thickness at least up to 6 or 7' or so, so. Since my shop is only 12 feet wide, reconciling these considerations effectively dictates that the saw be tight to one of the long walls, not somewhere in the middle, with the jointer (or planer, mine are separate) more or less opposite along the other long wall. My planer is in a wide doorway on the short wall between the main shop and shed, located such that the same clear space needed to handle the outfield from the saw also serves as infeed space to the planer. My workbench, which is around 5' x 2', occupies a corner of the main shop, off the outfield end of the jointer. Everything else is fitted around these main elements. The bandsaw is set up so its outfield goes into that same open area that serves the planer and saw. The drill press lives at the infeed end of the jointer. The router table is on wheels and scoots all over. Wood storage is in the shed, etc.
...It sounds like your shop will be a little wider than mine, at 5M, but I bet the basic principle of putting the saw tight to, and at the middle of, one of the long walls, with the joiner/planer opposite, determining a spot for the workbench, then figuring out the rest of the organization based on those anchor elements still holds.
