I have a epl-1, and you will be better served with getting the panasonic 45-200mm. It is a very fast focusing lens. And gives you a better reach then the olympus m zuiko 40-150mm.
For landscape shooting, the kit lens 14-42mm does a very good job. If you need wider angle to get large building into the frame the 9-18mm will be a good choice.
I would not get the kit with the 17mm 2.8 but the one with the 14-42mm zoom instead. The panasonic 20mm 1.7 is a better pancake for low light shooting.
