The first part, those are part of the Google maps stuff, and are being deprecated and replaced. I'll hopefully have a full release with those things soon.
Also, you can change the setting for API_SERVER from "geonames" to phpvms (search for "geonames" in the app.config), and copy it over to the local.config and change it to phpvms. There are instructions in there.
As for weather lookup, that's nothing I can change, you can contact the site which does it (I don't remember who it is, off the top of my head)
