For #2, try my script HighlightUsers, I made it to avoid long and annoying-to-maintain CSS files. Let me know if it works well for you, if you try it.

For the chat modification, do you just mean repositioning the sections for messages and the list of users? That shouldn't be too complicated, but I can't work on it at the moment.
