That car has been juiced for a while now, so I'd say you're very safe buying it and not having issues. The only maintenance I have heard of Ricky ever doing was the seals. I carry the seals for those cylinders if you ever need any.
As far as a road trip box to carry in your car I would get a small tool box and carry open ended wrenches in sizes 10mm, 1/2", 13mm, 9/16, 11/16, and 3/4. In addition to that I would carry a large (large enough to fit the end of accumulator) and a medium sized crescent wrench, phillips and flat head screw drivers, wire cutter/ crimper, wire connectors, spare sets of seals (hell even a spare 8" cylinder), a 15' hose and a 4' hose, a test light and a spare solenoid, and lastly the needed tools to remove the cylinders... probably a 17mm socket and open end and a 14mm socket. All that will fit into one of those small tool boxes and be easily handled.
All that being said.... you are more likely to use your jack and tire wrench to change your tire than anything on the hydraulic setup. Good luck on your purchase. That car is awesome and I know Ricky took really good care of it.
