Whether you need to escape a character in a regex expression depends on the regex flavour. In this case it is Python, and the forward-slash does not need to be escaped. If it did, the search expression would be " \/ " (Space backslash forward-slash space). But, escaping an extra character doesn't usually harm.

For the last one it is " & " (Space ampersand space).

And before you do this, everyone here would recommend taking a backup of the library. Simply close calibre and take a copy of the library directory. Then, when you mess up, you can restore the backup and start again.
