Hi Edward,
A couple of suggestion;
1-Chose a single working height for all of your work surfaces.
2-Get rid of most factory stands and build your own stands with storage space under for drawer or systainer drawers. Drawer give you 30-40% more storage space then low shelving. Mount everything on high quality casters.
3-Build the "Guido wall" on one side and a mobile work bench on the other side.
http://www.benchworks.be/tipstricks.html has some good idea you mount on casters. This should be placed at the entrance of the garage. Back of the garage to store all the big power tools on caster.
4-Unless you need your chop saw on site get rid of the stand and build a miter station on casters
5-File cabinets is out.Replace it with unit with smaller drawers that can be pulled out on each side, 4-8 cm deep. Great for router bits, chisel etc...
6-modular shelving 5-15 cm deep amazing amount of storage with small bins. Think narrow thin shelves spanning smaller distances.
7-Clamps store horizontally and in a box hinged to ceiling of garage.
8-Lumber rack on caster and with solid sides for the plywood level give extra storage space for guide rails, level etc...
9-Get rid of old tools and containers
That was my couple of suggestions good luck
