I am just hitting my 90 day mark with my new company, SunTrust Bank. My accountability is head of the DevOps Center of Enablement. All of what you are doing is what I am out to facilitate bringing to life. We are highly regulated and there are many who doubt that we will get to where you have gotten, but it is totally possible. One day at a time for now.
I would add two measures to what you have stated above (all excellent by the way).
Mean Time To Recovery - Mistakes and failures will happen. How often do they happen, and when they do, how long does it take to roll back?
Small Correct Change To Production Time - Credit to my friend, Kyle Griffin, for coming up with this name. This is sort of like cycle time under ideal circumstances. What this means is, make some really small and minor change to the last production release, say changing the words or labels on some web page, even in some way that is not humanly perceptible, like adding an HTML comment. How long does it take to go from committing to make this change to getting it out the door to the first production stage, and then to all production stages (for when you roll out in stages)? This is the best you can do under ideal circumstances. You want to keep an eye on this metric and endeavor to optimize it, so that when you really need to move this fast, you can.
