I think xed covered it pretty well.

I'd also mention that you should have some type of "keeper" on the clevises, like fuel tubing, to prevent them from opening on their own.

Put the plane on the ground or a table, stand a ways behind it and make sure that the tail is vertical, and that the horizontal stab is in line with the wings.

Mike Barbee is a well known name in RC. You're in good hands.

Good luck and have fun!
