Hey Pat!
Here's a pic of the bench I made with a retired woodworker back in the 80s. I made my armrests so they retract (slide in and out). I get kind of distracted when working sometimes and would probably be hurting myself on something like yours, plus there's lots of times I just don't want them there. It looks like mine might be spread out a bit more than yours. Maybe you could rig up channels they could slide in and out of?
I have a couple of holes drill in the front corners of the bench top that I can insert poles in to mount flexible shaft rotary machines and clip on lamps on. I also use a swing arm lamp. The bench pin (or V-block) is removable in that it has a tenon on its back end that slides into a mortise in the bench top front edge, such that the surface of the bench pin is flush to the surface of the bench top. I have made various inserts for different tasks, but use the basic bench pin for almost everything, particularly jeweler's saw, flex shaft and light filing.
I have two holes bored in horizontally either side of the bench pin. They are for inserting either end of ring mandrels. I also have a small thin "false-bottom" board that slides in and out of one of the main drawers for a retractable surface for jeweler's torch work.
I agree with Bill (nice work-spaces Bill!) in that I'd want to be able to get closer to the work via more overhang on the table top edge, or cut away space on the lower shelf so you can get your feet under and saddle your stool up closer. Speaking of stools, I really like one with a good back rest and quick release up and down adjustment. That way you can change your vertical relationship to your work.
The long open drawer in my pic doubles as a lap-pan. It is quite handy to be able to pull it out over your legs while working to catch gold dust and the occasional dropped precious gem. I don't work with that stuff much any more, but it's still a handy to hold the tools you're presently working with for any given project. I also like a raised edge surrounding the other three sides of the bench top to prevent stuff from rolling off.
A lot of this probably doesn't apply to you, but hey, any chance to show off.
All the best, Phil
