Hi Jeff,
Your understanding is correct. However, the parallel capacitor can go up to 300pF in some cases, even more (like 10uF) if you decide to significantly lower your resonant frequency. You will have to measure Rp of your particular coil to determine the proper rpmin and rpmax parameters. There is an empirical way to do this, see the FAQ.
For a 75mm coil it all depends on the gauge of the wire, and its expected inductance. You might find for smaller number of turns that the inductance is too small, so an inductor must be put in series to obtain oscillation. 1V pkpk on CFB would be a good indicator that the device should be outputting data.
Thanks,
