You're tight on space - like my potential trailer build. Let me walk through this mentally...
I assume the tick marks near 7 and 8 indicate a garage door? Going on that assumption, then:
A. New materials arrive and get unloaded to location 8, which is just inside the door. Very efficient.
B. Materials get broken down for width on the torsion/assembly table. Also very efficient, since it's close to where the materials are stored. I assume you will be using your track saw for straightline edging at this location.
Comment #1 - you could save some space by making your torsion/assembly table a little smaller - like maybe 3' x 6'? a little overhang is not necessarily a bad thing in this instance, so long as you have enough support that your offcut stays in place.
Comment #2 - Unless you are going to be buying only S2S lumber or sheet goods, I don't see a thickness planer? One of the 'lunchbox' styles could be easily added, and could go on a stand that you also use as an outfeed table or adjunct to your torsion/assembly table.
C. After cut to length, materials go to Mitre station to be crosscut to length. Or they could go directly here in the case of - say - dimensional lumber that you are going to edge join. Once again, efficient design.
Comment #3 - I don't see a glue-up area, so I assume that you will do multiple uses for the torsion/assembly table. Just consider the surface of the table then. I'd probably either wax it REALLY well or use a melamine coated material so glue can be easily cleaned off it.
D. Projects now move on for additional operations - dominoes, drilling, assembly, etc. These could take place either on the torsion/assembly table or your bench.
E. You mentioned that finishing will be done elsewhere. Can the paint cabinet move to that location?
Comment #4 - If it can't be removed from the shop area, I'd move it to location 3, which is a dead corner.
Comment #5 - the table saw is useless where it is. I know you said it is mobile, but you would have to move it virtually EVERY time you wanted to use it. Tell me more about what you typically use ( or intend to use) the table saw for and maybe we can find a better home for it?
Are there any interior doors, or is the only access (traffic pattern) through the OH door?
I think you've got a great start! I hope you don't mind my nit-picking it apart since I assume that's why you posted here.
