Jerry, I step my mast by myself, however, I do have a bit of help. I build an 8' long mast crutch out of a 2x4. It has a bow roller at the top, and a U bolt cut in half and installed as pintles to fit in the stern gudgeons. It holds the mast up at about a 35-40º angle. It's a bit sketchy rolling the mast base from the bow pulpit to the step plate, but not too bad, actually. From there, it's easy for me to lift to the fully upright position, because it's already been lifted maybe 1/3rd of the way up from flat horizontal. I always like to have 1 other person with a line tied to jib halyard to stand in front of the car on the ground, to hold it up once I have it full raised, while I attach the forestay. I find that I can lift it without the ground person pulling, but a little extra help is not unwanted. The mast will not stand unsupported without, at a minimum, the uppers and forestay. Because the uppers are swept, the backstay is not required to hold the mast up during stepping. However, I do step with backstay, uppers, and lowers attached. Last year, I unstepped by just loosening the forestay turnbuckle. I marked it's position with tape, but since I've messed with reinforcing my rudder headstock, the rudder blade is out just a few inches, and I need to re-adjust my mast rake forward, so it turns out the position of the forestay turnbuckle wasn't a big deal. Next year, I won't mess with anything, so once I get the helm balanced with only 3-5º of weatherhelm (hopefully this weekend) I should be good with my tape indicator on the forestay for next spring.
Not too sure what you mean about your jib. If the jib has a luff boltrope, then it's designed to fit in the slot of a roller furler foil. Something like a CDI or Schaeffer Snap-furl is ideal on the 192. The original jib was a wire luff furler, that had no foil that goes around the forestay. It had a drum at the tack, and a swivel at the head, and it pretty well sucked.
So, does the jib have a wire in a pocket in the luff? If so, this would be an original design sail. If there's a bolt rope sewed into the luff, similar to the main sails, but smaller, then it will fit into a foil. Do you have a foil and drum system that fits over the forestay? Pictures of what you've got would be helpful.
