They only matter if you are redistributing the same route into OSPF in multiple places. If there is only 1 route its metric is always the best no matter what it is. What numbers you pick will make little difference as long as you are consistant.
You don't need to define the metric value when redistributing into OSPF if OSPF learns theose routes from one single source.
Metric is used to compare OSPF route preference. If OSPF can learn the same route from more than one sources, you will need to see if there's a need to manipulate metric value to have the route selection as you want to.
You have router A,B,C running OSPF. Router A redistributing a route from EIGRP into OSPF. Router B redistributing the same route from static into OSPF. Router C will learn the same route from A and B through OSPF. Now you need to decide which is preferred. You can do this by setting metric values on Router A and B for redistribution.
