before you go do lessons i would grab a video camera and have a buddy tape you, you guys could take turns taping eachother. then go home and study the tape, it is very easy to spot and correct your mistakes that way, i know me and my friend have improved dramatically that way.
take a look at donnie hansens website dhma.com it looks like he has a school your way in july. he is an excellent instructor, he dropped my lap times 15seconds in 4days, really a great teacher.
