JT65B is what is commonly used on both 2 meters and 432 MHz, however many stations use CW as well. In the microwave bands, with a large station, SSB is possible.
Search for the WSJT program and I'm sure you will find lots of information. The frequency range commonly used is the lower portion of the 2 meter band, below 144.200.
Moon bounce with circularly polarized satellite antennas is not very easy as almost all EME stations use either horizontal or vertical polarization, so using circular polarity will add additional loss, although I have made a couple of 432 EME contacts with my M2 circularly polarized antenna and just 50 watts from my TS-2000. However those contacts were with some very big big-guns, but don't let that discourage you!
