In regards to #5, worth pointing out that some coworkers are probably just as disappointed with the current state of affairs as you. They would probably really appreciate somebody pushing them to hone their craft.

Also worth considering that some people never learned how to handle constructive criticism and will take any suggestions as personal attacks. Stay as far away from these people as possible, you aren't going to change them but their pettiness can make your life miserable, particularly if they're closer to management than you are.
