I don't hammock but I've looked into it a bit and know these guys are popular for suspension: https://whoopieslings.com/

A space blanket hung underneath the hammock might be good enough for under insulation (stuff with dried leaves if you get cold).

The walking stick sounds like a pound of nostalgia to me.

You have a battery charger and batteries and two light sources (three if you include the phone). Seems like an awful lot of redundancy for electronics. How important are the electronics to your enjoyment/safety?
