E2 routes are the default.  You need to specify the metric-type when redistributing rip.

redistribute rip metric-type 1

Yes, E1 routes append the internal cost to the external cost.  E2 routes only use the external cost.  Use E1 routes when you have multiple exit points to an external autonomous system so the best path is used from the inside.  If you only have one exit point, E2 routes are fine.
