Move the bottom of the shocks out one hole to lower it down a little more. The ideal stance is for the driveshafts to be straight across and parallel to the ground. If you do a lot of jumping, then leave it just as is. If you bash around and have fun, them move the lower shocks.
and for the alignment, you will not touch anything on the front end. Put a straight edge on the rear tire directly in the middle of the tire where the wheel nut is so that it is touching both front and back of the tire. Now, adjust the turnbuckle for that wheel until the rod that is sticking out to the front comes up and just touches the sidewalls (plural, you want it touching both so you know it is perfectly in line and will track straight) and then take the rod off and add about 1.5 complete turns to the turnbuckle to increase the toe in. Then do the same for the other wheel.
It sounds complicated, and it much better explained in a video, I just don't have the time right now to do is, and it is towards the end of the series since it is part of the setup process.
