Hello, looks like you have a good starting point for a restoration.
Many items needed for a machine that old to make it reliable and safe.
Depending on budget available can influence how deep the restoration goes, and your level of expertise, what you can perform and what you need to have done for you.
I think all possible trouble- spots should be inspected, cleaned, lubed, or replaced. Things like cables, wheel bearings, swing arm bushings, tires and tubes, steering head bearings, chain and sprockets, brake pivot shafts.
Modern upgrades, like regulator/rectifier update, (a major charge system improvement) or electronic ignition, modern ignition coils that will make it a 1 kicker.
All that and we have not mentioned the engine.
I would expect that 50-year-old gaskets and oil seals need replacement, with a close inspection and cleaning of all engine components. Disassembly of cylinder head, removal of valves, clean and inspect, repeat...4 new cam bearings, new cam chain.
Its not hard to take a year to complete depending how detailed you get. The trick is to accept delays, they will happen, take your time, and try to enjoy the process.
