If you want to prevent casual reads with user tools which don't physically destroy the hardware, a single overwrite is probablt fine. If you think someone would want the info enough to take the drive apart, encrypt everything including swap and tmp, using DES3 or similar extremely hard code.
You have to know your exposure, who will try to recover the data and how hard they will try.
