Not sure about that Phone Manager stuff but there is the Nokia PC Suite available for free download off the Nokia website.
If you load that up and connect the data cable then you should (if memory serves me correctly - I'm on a Samsung at the moment) be able to save your phone's profile or do a backup?
If not, then you can definitely copy the ring tone onto your PC and the logo. I mucked around with mine for ages when I had a Nokia 6610.
