Would blocking port 135 at the network edge be a prudent preventative
measure?

It depends.

  Do you have a network edge?
  Do you have the resources to block it?
  Do you need it for anything else?
  Have you left other holes open?

In reality blocking port 135 is almost never sufficient.  Its slightly
better than waving a dead chicken over your PC.
