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.
