We were looking at getting 14 SolarWorld panels, in a grid-tied system. Not sure about the inverter, yet. We don't have nearly enough un-shaded roof space to go completely off-grid. We got a quote from http://www.solarcity.com/, who have been doing a pretty big push in conjunction with the city of Beaverton. The slickness of their sales pitch is a bit nauseating. We also got a quote from a local (reliable) contractor, which was ~$600 or so cheaper. As for monitoring, the most interesting product I've been able to find has so far been a TED-5002.
