Olympus OMD and lens suggestions please

I think I'm ready to pull the trigger on the Olympus EM-5, especially with the Amazon rebates right now.

I'm not doing any pro shooting, just pleasure: my kid, family, vacation spots.

I'm still a newbie and am planning to take a class after I get the camera so right now I don't know a lot about the different lenses. From my reading, it sounds like I should get the 45mm/f 1.8 but should I get another lens to round it out? Something wider, something with a zoom? I'd like to limit myself to 2 lenses for now.

Thanks in advance for any advice.
