Mark Lauterbach of Grace Church San Diego is preaching through Ephesians at the moment. Not had a chance to listen to them yet but Mark is a brilliant example of gospel driven ministry, and the author of The Transforming Community. I expect this worth adding to your iPod - they're going onto mine.
Some of the series is by Eric Turbedsky who is also excellent.
Meeting both of them ranks among the many highlights of going to the USA last year.
I worked through Ephesians a couple of years ago - notes here
