That's a complicated question.
you can use the standard FEFF of the PbO to simulate first.
As for the guess, you can set some varibles as fixed, which are most likely. And then tune the others.

The best fitting result should see the k fitting results, not the R fitting. Only those fits both k and R well are acceptable.

I cannot judge anyting from the data you provided. The following is the sequences to fitting with Artemis:
1) make sure that you calibrated the data well using calibration software,such as Athena, or something else. Make sure that the data are k3 weighted.
2) open the file in the Artmis, set the Fourier and fit parameters you need. You'd better use the Kaiser-Bessel mode, and fit k weights as the K3 weighted.
3) Then go to theory. Since PbO has known crystal strucutre. you can make new atom page and edit the FEFF of the PbO---Run atoms. then you can get the atoms code, run feff to get the feff.
4) then try fit by modifing the varibles. you'd better free the DB factor first and set some others.

Hope it helps.
