Glad you feel good! The first picture you foot in not parallel to the ground. If it was, I would say you are the the max height for extension. Once you get the new stem, mark you current position and fiddle around a bit.

I would say your KOPS is still ab bit forward. Get a seatpost with some more set-back and you will be happier in the long run. Or try a Fizik saddle with longer rails for more adjustment.

Again, fit is very subjective and fiddling with it can sometimes yield great or worse results.

Good luck!

And here's the horizontal position again
