John:
The ASW17 will benefit greatly from a one-man rigger.
As noted in a prior thread about ASW20 ballast bags, if your bags are shot try sending them as a template to RPR.
Regarding the ramp jack, have a look at one of the "Uncle Fuzzy" trailer mods which is an alternative method to hydraulic. He isn't with us any more, but the videos are. Link below.
Many original 17s had insufficient wheel brake. Believe some people fitted a Blanik wheel/brake, which should be readily available now. This was addressed in the 17B with dual drum brakes. An alternative is to get a motorcycle shop to reline and arc the shoes. For example, Vintage Brake in Sonora, CA.
