If you install a new version, you may have to install new libraries also. This may impact other softwares installed on your system. You may introduce new bugs, or regressions. This is at your own risks. Don't ask me about the probability. It's probably low, but I have not tried. So I have no idea. You just need to be aware that this is a possibility.
This said, I understand your need, and I would probably attempt to upgrade R if I were in your position.
I have Linux Mint Debian Edition and therefore I have already R 3.1, so I don't face this issue.

As a workaround in Linux I add the line Sys.setlocale("LC_MESSAGES", "en_US.UTF-8") into Rprofile.site. Unfortunately starting messages is not in English.
No idea. I have never tried to change this. It's in french for me and that's perfect.
