Hi Al,
A good start. Read the replies below for more advice. There are really three kits that you might be describing:
1. A bug out bag -- grab and go, designed to get you someplace else
2. Bug in gear ( see also 'shelter in place') staying home during an event. This group is mostly food/ water and some confort items
3. A car kit. tools ( and fluids) for keeping a car running
