Everyone is different.
Here was my checklist:
1. Got together a wardrobe of clothes that look attractive on me. Along with some accessories, purses, shoes, jewelry etc. This is NOT a cheap proposition. You will spend a lot for clothes you think might look good but then you figure out they don't. I had some very honest friends I would model for and they were a huge help. It's hard sometimes to judge for yourself. I highly suggest starting at a thrift store or big discount sale items at least till you figure out your style. I also started to incorporate some of these into my daily wear for a fairly andro appearance.
2. For me my natural hair was -all- gone many years ago so the only realistic solution was a wig. I went to a wig salon with same friends and tried on a zillion styles before I got my first. I've changed styles 2 times since then but am happy now. Very comfortable, not hot etc. I have no issues now with this at all. Of course I would rather have pretty natural hair but that was not an option for me.
3. Learned to do decent makeup and found a bra/form that fit my statue so my body at least resembled a females. Figured one day I would either grow some or get a BA or both.
4. Started living full time i.e a new life

. I just decided I had enough of living as a man and after a few weeks of part time going out as a woman, just started doing it all the time. Really had no huge issues considering I was basically pre-everything. I also got my name changed very soon after this. Living full time with male name ID isn't a good plan lol. If I did this over I would have started the name change before I went full time.
5. 2 years later started HRT.
6. 6 months after that got nose job to fem up my face.
7. Started voice lessons 1 month after nose job. The biggest mistake I made was I should have dealt with my voice as one of the first things. I notice on your timeline you don't have voice even mentioned. It's a big mistake most people make in their transition plans. IMHO it should be the first thing you have on a transition list as it takes a long time to perfect.
7. 1 year after hrt (only AA, had issues with estrogen I'm still working to resolve) 90% of body hair gave it up. Some light laser treatments killed rest of back hair, shave legs (which most women do) and a bi weekly shave of other parts keeps that in check. for arm hair just a "hair trimmer" set to lowest setting works fine.
8. Even with my limited HRT, boobs are filling in and about 1/2 of what I hope/planned to have for my body type. Skin looks nice etc.
9. Going to have some laser facial hair work done and then maybe try electrolysis again. Then again after a morning shave and light makeup, I have zero beard shadow so might not.
10. GRS? Not sure I might consider it at some point or at least a orchi to avoid the AA meds. Not a huge priority for me. My goal was to live and be treated as a woman and I've been doing that for several years now.
As far as regrets. I should have started my voice training as the first step and started the name change months before I went full time. Otherwise I wouldn't do anything different. By the time I started HRT etc I KNEW what living as a woman was like and knew I was really happy.
As far as my take on your list which I suppose was the reason you posted it:
First step should be start working on your voice.
FFS, I have no idea what you look like so not sure what you do or don't need. I'd suggest as little as you can get away with but that's your choice to make. IMHO things beyond basic nose/chin shape have a very limited return vs cost/recover/risk. I can say most cheek implants and lip enlargements don't look attractive to me. There are plenty of thin lipped narrow cheek women in the world who are still attractive.
Facial hair, if you have dark hair/white skin you're right that this is a must by whatever means needed.
Hair transplant, if you can get a natural head of hair doing this that in the end will look good, go for it.
Genital hair, that again is up to you..
Body hair. I would NOT bother with this until you are sure HRT isn't going to take care of it. For some people it can take 2-3 years but finally does. It's simple enough to shave/trim area's until HRT does it's thing. Women do not have hairless bodies, like they have to shave their legs and arm pits etc.
On the hair on your head, I've heard bad results from most extensions and how long they last etc. Doesn't sound much better than a wig to me, YMMV.
On if you can live full time at this point, I did it before anything on your list so.. that again is up to you.
Hope this helps!
