Doug:
You should get the same results if anonymous access is allowed, so I'm not sure what's going on. However, since you are setting k = 0 before the call, the SPServices call may well be getting an error which you would never see. (There would be no z:row elements in the error.)
You should look at the returned XML to see if the call is successful. You can add an alert into the completefunc - alert(xData.responseText); - or better, look at the Net traffic with Firebug or Fiddler.
