to raise orbit you need to increase your orbital velocity, which is why you need to fire thrusters along the direction of the object's motion
this is how satellites reach geostationary orbit, they use a first maneuver to increase their orbit's aphelion to the geostationary altitude then once they reach the aphelion they do another maneuver to bring the perihelion to geostationary altitude as well
applying thrust away from earth would do jack shit, as you have Earth's gravity countering that force and the only thing it would accomplish is reduce your orbital velocity
