No, you should ask yourself if you need to provide r-services (RPC/NFS/NIS) to others. If not, close down those ports by I. adding a rule to your firewall, II. stop the rpc daemon and III. deinstall the packages (portmap.* nfs.*) and remove their configs (also look into xinted while you're at it), else try to tighten access by reading this for example.

Reviewing and adding firewall rules and adding rules for TCP-wrapped services will help stop ppl accessing services you don't want them to are good but remedial to say the least. What you "really need now" is to review what networked daemons you have running/installed on your system you don't use *now*. Look up tldp.org/ www.ibiblio.org/ google the net for "Securing Optimizing Linux RH Edition".
