If you haven't done any update to the firmware that came from the factory that could be your issue with the wifi. The Kobo Touch firmware as shipped doesn't (didn't on early ones anyway) have wifi capability as the wifi functionality wasn't completed in time to make it into the firmware installed at factory. If you do a firmware update from link PeterT suggested that may solve your wifi issue. Aside from that you should be able to do everything without a Kobo account. You would need an Adobe Digital Editions account to use DRMed content (unless stripped) though.
Having said that, I'm not sure there is currently any option to export annotations.
