While a cable connection might be a more attractive target to crackers
than a dialup connection, breaking in on a cable-connected machine is
not easier than breaking in on a dialup machine. 
What I would do (I don't since I have a dedicated firewall machine) is :
- close all unneeded services
- install a firewall that just drops any incoming connection from your
  cable-connected ethernet interface. (I would recommend using fwbuilder
  to build the firewall script. I have used it on my small home
  firewall, the firewall at work, and at several customer sites,
  including one with 6 subnets. I think it should also work well on a
  standalone PC, although it might be overkill)
