Re: Redistribution

Adding to Ravi's reply,
for #2 you can imaging an OSPF in your case doing the following

redistribute connected subnets route-map RIP-INTERFACES

route-map RIP-INTERFACES permit 10
  match interface FastEthernet0/1

this is in addition to normal redistribution and is done automatically.
