The mod I've done that has given me the most straightforward satisfaction has been swapping the Z threaded rods for metric rods. It's not a critical mod by any means, but it does two things very well and without fuss. First, it makes the selection of the Z steps per mm very simple. The exact number depends on which size you get (I bucked the M5 trend and went with M8.) No more weird floating point numbers, instead a lovely integer. Second, it allows selections of level heights that don't fall prey to the dreaded ribbing math (see for a great write up.)
Certainly I agree that this is less important than a flat printing surface, but once you've go that under control, consider trying out some new threads.
