Do I need stats?

Probably not.  If you can access raw logs, you could download them and analyze them on your home computer with a stats program yourself.  However, the log files can get quite large for popular sites, so having the server analyze them may be more convenient.  You could also use a service like WebTrends, theCounter.com, or Site Meter to get more detailed stats on your users than any host's stats program can provide.
