Simple Nokia n810 questions.

Guys:

I'm thinking about getting the Nokia n810 for web work and GPS mapping.
Just have a few questions that's hard to find on the net. This should be easy for someone that owns the n810 and bought 3rd party map & chat clients.

Does the n810 have Nokia Maps 2.0? Any free maps available? I hope to get World wide coverage (I travel a lot to remote areas outside Americas/Europe). I don't care about traffic direction maps, just streets and a dot showing where I am. I don't need or want Wayfinder.
Do I need to subscribe to the map service? Something like $40/year or can I just buy the maps once?
Google and Microsoft maps are good, but I can only use offline maps.

Does the built-in web-cam work for online video chat? Can I use video-chat with MSN Messenger or Skype? Or I can only use some less known app like Gizmo? There was lots of questions and trouble about this a year ago, but I hope things have changed a lot since then.

Thanks!
