First off, don't be abrasive and condemning toward what he wants. I know that it sucks, but the last thing that you want (and the first thing that Satin wants) is strife withing your group. So while you might not like the fact that you HAVE to play root notes and that you HAVE to wear a suit and tie, do it and don't complain. But this does not mean that you can't try and change his mind, but there are constructive ways of doing this. First, try learning the bass lines to the songs that you are playing, he might like this (I have worked with leaders in the past that didn't care what you played, but LOVED it when you played the lines as they were written). Second, ask him if you can try out some of these lines IN PRACTICE -- to see if they add anything to the song -- don't just learn the lines and throw them out in a service. This would be undermining those that are in authority above you. If this flys, try a few variations and what not. I must add that for most songs in most situations I have found that root notes are the best thing in a worship service.
Now about the dress, find some scriptures on appropriate dress. Focus on the ones that are found in the new testament.
It may suck, and I am sure that it does, but you have to deal with it and give it up to God. Do not let this become something that causes strife within the group.

It has taken a lot of fun out of being the bass player. He has also demanded all musicians and singers be in "coat and tie" or "dresses" for the ladies when on the platform. Before he came we were allowed to be causual but neat.
