If there's no map on EQ2MAP for the zone then you can't submit POIs -- unfortunately not much to be done about that aside from waiting for the maps to be imported, and the person with the access to do so hasn't had a lot of time lately.
As for the rest... I'd have to test it myself, but IIRC it's always been a touch flakey with the in-game browser with logging in. That's always been on SOE's end. I believe the old workaround was to log in on the EQ2interface side and then go back to the EQ2MAP page.
Edit: Just tested logging into EQ2MAP via the in game browser and didn't have any problem.
