I think that the anxiety and the pack leader role are two separate things. Each that needs to be dealt with in different ways. As for teaching him that you are the leader I think that teaching him his commands (sit, stay, & here) and to listen to you will go a long way in solving this issue. Making sure that he know you are the teach/leader and what you say goes. Not allowing him to not do as you ask of him is a good way to start. Making sure that he understands the commands and does them the moment after being told. If you should allow him to test the limit and boundaries you are allowing him to take control. Always have him leashed when working on your commands, that gives you control of the situation. Two to three 10 minutes sessions a day will work wonders.

The anxiety issue normally stem from being left alone too often or for long periods of time. At least that is how I understand it, being a stay at home mom I don't know much about it. I would suggest making sure he has plenty of toys to keep him busy when you are way. And also working with him doing some behavior training in some quick leaving and reentering the home exercises. Rewarding him for having a calm demeanor before you leave and reenter is very important. Always reward the good behavior and ignore the bad. I've seen it done before and it seems to work.
