When i started out i watched and read mutiple things as I didnt want to do the wrong thing either. I pulled the common points out and the stuff that just logically sounded right and then went for it.
Fwiw, wipe the pf down, then use some novus 1 to lightly dampen a towel, rewipe pf and all plastics and basically everything to get the coil dust out.
I apply the wax with my fingers (only to PF!) let it sit a couple minutes then start rewiping it all down with new dry towels, usually a couple passes to get all the wax off and kind of polish it a bit. You can def feel the difference afterwards.
Make sure to clean any errant wax off posts and targets etc.
