Astra,
I'm providing this advice from the other perspective. I am a manager and I must tell you - DO NOT confront the boss or come across negatively. Unfortunately from your description, you're current boss doesn't seem to have good leadership or people skills, which is a big problem - especially for you and your co-workers.
Although, I'm a manager, I've worked for some pretty bad bosses in my day. I always observe the boss and try to find strengths (or something I like about him/her). I take this approach for my own sake. If I can find something positive to relate to my boss, then I also have a positive starting point when I have to deal with something I don't like.
If I were in your shoes, I'd try to learn the boss's expectations. Also try building a working relationship with the boss. If you can show your boss how you are a positive asset to helping him/her achieve his/her goals, then that's a huge step in the right direction.
