Not sure what unit you have there for the heat pump.
But when they say----there are two diagrams-hp/elec heat using a humidistat for dehumidification, and the other says hp/elec heat using a 2 stage thermostat for dehumidification? which diagram should i use?

Most of the time that is on a V/S blower for the AC part. When set it will slow the blower down so it can pull more humidity out of the air for you in the summer. Both say DEHUMIDIFICATION. Not to put humidity in the air. That 700 came with its own humidifier control put it on the cold air drop and use the manual mode

Only if you have a 2 stage condenser unit
