By your questions it appears you are interested in finding out more 
about eme (Moonbounce) but do not know very much about it.

On 2m eme is conducted in the 144.030-144.100 sub-band for CW, and on 
144.100- 144.160 for digital eme.  Psk-31 is not used and not really 
suitable.  A mode called JT-65 is used for digital eme.  It is a 
narrow-band FSK mode using software and computer soundcard to drive a 
SSB 2m radio.  An excellent article on eme is in the current ARRL 
Handbook written by Joe Taylor, K1JT, author of JT-65.  This will 
answer many of your basic questions on what eme is and how to get started.

One cannot decide today I am doing eme.  Where do I transmit?

If you have a good satellite or terrestrial 2m yagi and at least 150w 
you have the basics to start.  But there is a lot to learn before one 
should expect to work eme.  There is the basic station 
setup.  Tracking the Moon.  Frequencies and procedures used.  As you 
get into it quite a bit to coming up the learning curve.  Give 
yourself at least a couple months to accumulate this knowledge so you 
are better equipped to try eme.
