Proac 2.5 Response tweeter upgrade with Ribbon Tweeter?
No idea on the matching, but I owned a pair of 2.5 and now own the D40r with ribbon tweeter. Much better speaker. 
Metal cabinet speakers
Wilson Benesch has metal and carbon fiber cabinets. Very low noise 
Your favourite music movie?
Spinal Tap - Best rock music parody+1 for Stop making Sense - Just a great show by the Talking Heads+1 for Live and Die in LA - Great action movie with an interesting soundtrack from Wang ChungAmerican Hustle is a great movie with soundtrack to match 
Soundlab A3s and thoughts.
I know two people that own Soundlabs. One uses Red Rose tube amplifiers and the other uses Wolcott tube amplifiers.Both systems sound greatGood luck with your SoundLabs 
New efficient speakers - best way to keep noise floor down?
What is the rest of your system. The way the noise floor gets reduced is equipment with equipment that has low internal noise levels. A quiet phono stage is a good start, but you also want a preamp and amp with low noise levels. 
Turntable Advice?
roberjerman+1 on the new motor from SOTA.OP, none of the turntables mentioned have a tonearm as good as your SME 
I can buy a pair of Sanders Innersound Eros...
I don't know in comparison to the ML speakers, but I have heard them and the sweet spot is small. 
Let's roll: what pre-amp tubes should I consider next?
RCA cleartop 
Tube or monos for ProAc Response 48D
I would probably prefer the Dynaco although I have not compared the two. Currently using the Luxman MB-3045 on Proac D-40r speakers 
Audiosilente idler wheel versus Artisan Fidelity idler wheel for a Garraed 401
The OP transposed the pricing.Audiosilente $100Artisan Fidelity $365OP, do a search I think @noromance posted a comparison between the two and like the Artisan Fidelity better. 
Buy a pair of ten year old $40,000 speakers for $4,000 or new ones at that price point?
How about some examples of the $40,000 speaker now available for $4,000? 
Caster Wheels vs. Spikes
I don't think casters would detract from the appearancehttps://www.audiogon.com/listings/full-range-tekton-design-llc-double-impact-soft-gloss-black-newly-patented-design-2017-05-12-speakers-84058-vineyard-ut?creative=305983658573&gclid=Cj0K... 
Suggestions for my next upgrade
Get the speakers you like then select the amp. The Quad amps will not be a good match for most of the speakers you have listed. If you don't like the way the speakers look buy something else, same for the sound.Go to a show, maybe RMAF in the Fall... 
Broken stylus for Soundsmith MIMC Zephyr Star Repair????????
contact soundsmith and send it in for repair 
Proac D40R or Monitor Audio Platinum II 500
I was using an Aesthetix Calypso and Atlas (which were very synergistic with the speakers), but recently changed to a Luxman CL-38u and a pair of Luxman MB 3045 (circa 1975) factory converted to use 6550 tubes).
