Just to clarify, Safari 4 and prior were standalone apps that could be easily deleted and replaced, but Safari 5 and later sink hooks deep into OS X and cannot be dealt with so easily other than by reinstalling or restoring OS X.
Jon is correct about your likely losing data if you restore from Time Machine, so if that's an issue you'll have to travel another route. (Note, though, that if the e-mails with which you're concerned are still stored on your mail server you can retrieve them after restoring.)
