Greetings!

Regarding the first question, that's still an open issue:

  https://github.com/Unidata/MetPy/issues/262

This may be more readily achievable now using Matplotlib's "secondary axis" 
functionality:

I've answered the other questions on your Stack Overflow question:

  
https://stackoverflow.com/questions/67664575/metpy-hodograph-place-point-at-specified-wind-data/67681531#67681531

Hope this helps!
