Welcome!
Your previous experience will be of benefit to you in your new projects, and probably to others on this forum. (It has members covering an immense range of interests and experience.)
If you are new to machining metal, may I suggest reading “The Amateur’s Lathe” by L H Sparey, “The Amateur’s Workshop” by Ian Bradley or the books by Stan Bray and Harold Hall? (The latter has writtren books on both latheowk and milling.
FWIW, my advice is to start by just nachinging bits of bar in the lathe to become familiar with the latyhe, and then to make simple tools, (centre Height Gauge for a start and then a sliding Die Holder for the Tailstock, A drill chuck could be made, to slide on the same arbor, to act as a sliding Tap Holder. Then, follow up with a mandrel handle, which will be useful for use with the Taps and Dies.
You will gain experience and confidence for the bigger projects which follow, and have useful items, ehich make life a little easier.
Riding another hobby horse, it will eventually be worth making a rear toolpost for the Myford. With the tool held, inverted in it, parting off will be less fraught.
Good Luck!
