This is a common problem. Yes, there are such tables, in various
mechanical (and sometimes chemical) reference books. You'll have to go
to a library and do some research.
No, you can't multiply or sum them and expect the results to work. Each
pair has to be separately measured, so you need a big table.
Last: ODE does not model rolling friction, only sliding friction. Thus,
you have to apply inertial dampening yourself to model rolling friction.
