I am considering the purchase of the PSM wireless monitor system. To operate 4 mics with four individual monitor outputs for each vocal what would I need to order in components? The P4MTRE1 pack comes with the transmitter P4T, one body pack receiver P4R, one personal monitor mixer P4M and one E1 earphone. Would I assume that I would need to order three more body packs P4R and three more E1 earphones? Do you put together these types of packages?

If you want to send one stereo mix to all four singers, you require the following: 1 - P4MTRE1; 3 - P4R; 3 - E1.
But if each singer requires a different stereo mix, then the price and complexity of your system quadruples. Then you need 4 - P4MTRE1 with each adjusted to a different transmitting frequency.
