We just got our MH back in August 2010, but did drive it just briefly after dark one time, and our lights are not aimed correctly either. It has been at the dealer since October for some other unrelated warranty issues, and we told them we couldn't go South this winter, and they know this.
The low beams were not bad, but the high beams were ridiculously aimed poorly.
Regardless of what an "aiming station" may indicate, it's my intention to take the MH to a vacant spot sometime (somewhere with a wall to focus on) and adjust the lights where I want them a certain distance from the wall. I have done this many times before with an assortment of vehicles. It's a matter of playing around so that I do not get opposing traffic flashing their lights at me because they are aimed too high or in the wrong direction.
The adjustment screws you show in your photo seem to be identified correctly. On a dark night, small adjustments to these screws, will confirm if they are in fact the up and down, and the side to side adjusters you're looking for.
