One thing to be careful of is that some of the "integrated harnesses" you find on PFDs, like those sold by Mustang, are not designed for short people. In the fine print, many will say what the minimum height is, and it is often 5' 8". The reason that these harnesses are not safe for shorter people is that they will ride too low and be sitting over the floating ribs and if you fall, they may cause serious internal injuries.
As for jacklines, the best ones I've seen were 1/4" spectra run through 1" polyester flat tubular webbing. Whatever you use for your jacklines should be readily distinguishable by touch as well as sight, so that you don't clip in to something else by accident.
