I suspect you have 100K ohm thermistors, but that's not really your issue.
You will need (as a minimum):
1) The correct steps / mm settings for your X,Y,Z and E motors
2) A rational set of maximum feed rates (try 200,200,2,40)
3) The correct end stop types for your end stops (min or max)
4) The proper home directions for your switch locations
5) The right thermistor table for the type (brand) of 100K thermistor you have. Table 1 is a good bet.
6) The right main board number for your Rambo.
Once you do all that, grab a volt meter and set the Vref's properly for the current rating of your motors.
