Keep in mind that it has been 10 years since I turned wrenches (for REME at least) so things may have changed:
1) In my experiance, no. My time as a maintainer counted for exactly zero as far as getting a civvie certification went. Perhaps I never looked in the right place or asked the right questions... but nobody ever recognised my qualification on civvie street.
HOWEVER, I find that successful maintainers make good mechanics, better than the average output from the trade schools. If you can get a foot in the door, you're likely to do very well because good mechanics (as opposed to parts changers) are hard to find these days.
2) It is possible to be promoted higher than MCpl as a maintainer, but it can take a looooong time. There's just not that many positions open. Your typical first line LAD will have 2-3 MRTs and a wrecker (each with a Cpl/MCpl crew commander) a Sgt as 2IC, and then a WO as the ETSM. Even the Service Battalions don't have that many open slots past MCpl (1 Sgt, 1 WO per platoon, then a MWO as ETSM) And (at least in my day) you didn't make Cpl very quickly either, as QL4 was OJT and the QL5 course was another 6 months in Borden.
Promotions happen much sooner in the combat arms.
Now on the plus side, the life of a maintainer was pretty good, especially if you were attached to an armoured unit. If you have any brains and interpersonal skills at all, you are treated as a valuable resource (except back at battalion, especially in Vehicle Platoon) and when working on vehicles, you have more effective "rank" than what is actually on your shoulder. Plus, especially in Recovery, you get the opportunity to make fun of the guys who got their tracks stuck. I really enjoyed being a maintainer, and having those skills handy have saved my hash a couple of times. But if you're looking for rapid promotion, 411 ain't it.
