This sounds like you are doing a lot of inserts followed by a lot of
deletes. That's not bad but if performance is down, then I'd look to indexes
as the culprit.
Backup nightly, test restore nightly too to a separate location, but no, you
don't need to restore to the live system every noght - total waste of time.
You need to look at the Indexes with the specific queries in mind. If the
application code is not accessible to you, i.e. you don't know the exact
queries it is using then you'll have to make some intelligent guesses on
what fields to check for indexes or add them where missing.
