Only you can answer that question.  How badly do you need to get the server 
back up and running?  If it's not critical, it would be worth taking the time 
to investigate.  Otherwise you'll set it back up the same way and be hacked 
again in the same way.  If you know someone who is good at forensics on Unix 
boxes, call them.
