I don't think anyone has replied here because they don't want to touch this issue. When it comes to cross-browser compatibility, some people start thinking suicidal thoughts. I don't currently have time to check out all your issues that you've listed but I will give it a shot when I get home from school, however, if you want my advice, what I do is code my designs in Google Chrome and then go back and check the other browsers. Safari usually works very similarly to Chrome and Firefox isn't too bad either. Internet Explorer is always the one who has the odd issues but you can usually find a workaround for it by Googling the issue or asking here.
