How to get healthier hands and smoother feet?

Push back your cuticles, see a doctor about the hangnails and use a lot of lotion of those feet. Try the ped egg or a pumice stone followed by a foot scrub followed by a moisturizing lotion for your feet. Keep your nails trimmed and straight, that will solve your hangnail problem. I mean DAMN, you sound like you have the feet of a monster lol.
