The first problem.
Make sure you are not still a member of the Moderators group. Then bring up your name again in the Forum Admin adn make sure ALSO that at the bottom you do not have the Special Rank of Moderator. Change your Special Rank to Admin.
Second problem I believe has been fixed in the new 2.0.5 ported forums and 2.0.6 upgrade at

To work around the issue, remove yourself from the group your are in FIRST, then update your Forum premissions, then add yourself back to the group you were in.
