Neat. I have removed the hard top like that before - and I am about the same height as you weighing 12 stones, but I almost dropped it once because I didn't balance correctly. Besides, if I did it like that I wouldn't have any space to put the jeep - now I can park the Jeep under the roof, saving space. I also have a big motorcycle to cater for in one parking square.
I don't use pulleys. I hang 4 pieces of rope from the beams where the corners of the roof are when the Jeep is parked. I have attached metal hooks to the end of the ropes. I just lift the front part of the roof onto the hooks, and then do the same with the back so the roof is suspended, and then I reinforce the ropes by supporting the underside of the roof with tow lines, also hooked onto the ceiling.
That's a nice Jeep by the way, and a very nice colour. What are your rear lights - thy're non-standard?
