As Stuart says there are many variations on several themes and a definitive guide is not really possible.
However your composite Tales I would think is fairly standard.
A one string conversion on a JT boat isn't a drama and you can pretty much copy the winder layout - if that is the way you're going.
In any case the "hard working" parts of the main rig cascades should be dyneema. 3mm 12 strand is fine for a 6:1 as original, 4mm is better for an updated 3:1. The secondary parts are fine with 3mm12 strand. I find 2/2.5mm a bit thin and mincy.
Control lines should all be 4mm. I always use dyneema core on the shrouds and lowers. The kicker wants to be continuous ideally. If you're not one stringing the shrouds and jib halyard should be too, this will make a massive difference to your sailing (I did this on 3583 before its conversion and it was a revelation).
Pole downhauls - 2mm 12 strand dyneema, then a 4 or 5mm control line. This takes quite a pull. Again I'm using dyneema for this and ive upped it to 5mm. What you use will depend where it is and how the woodwork allows access.
Spinnaker sheets usually come out at 13.5m, jib sheets 8.5 (This varies hugely due to taste) and a mainsheet is 8m. If tapering beware of shrink post taper - its amazing how much length a taper uses up!
Use of decent rope brands will greatly improve stretch/shrink resistance, you do get what you pay for.
I've got lengths for a one string job, but not the older fit out.
