For the stalling issue, the throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean.
The dead speedometer could be a bad stepper motor in the instrument cluster or a bad speed sensor on the transmission. If the cruise control is not working, the problem is most likely the speed sensor.
