This is just my personal viewpoint.
Hair on the face and that includes a shadow is a huge no no. From there, one ought to find a solution that works, be it laser, electrolysis, both and or other.
Voice feminization is another area that is essential, though I would place that under the facial hair removal in importance to start early.
Both these areas will likely take about two years to achieve.
As for surgery, that is very expensive. Your question as to whether you need facial feminization surgery depends on your genetics ... the strength of your male genetics ... how male you look.
Same with the voice ... if you sound like a tenor then yeah, it MIGHT well be an issue.
I live as a female already, but pass as male and look androgynous. I am happy where I am at. It is the best I can be at this time, and being gentle and kind to oneself is important.
I think a transition from a good genetic start would take about five years. However if one is 6 foot 2, 100 kgs, sings tenor in the local footy choir, can bench press a mini, has more hair than singer Prince, and a face like Mount Rushmore, then yeah ... it would probably be easier to canoe up Mount Everest!
Again, these are just my personal views. We each need to make our own way forward, but never, never - ever give up.
