Well for a kick off you'll find it more fun in an Arrer than a 150 – more knobs to twiddle and buttons to push. Oh yeah and a damn sight more comfy too especially if you are of Rimmer dimensions (6'3 and a svelte 16 stone).
The only real trick to the Arrer is leaving just a smidgin of power on until late in the flare (drops like a brick dirtied up at idle). The other thing is it will probably seem like a ridiculously fast pace to blat around the circut to start with (I usually reckon on 100kt downwind, 90 on base, 80 on final slowing to 70 over the fence) . If the circuit's busy you'll be introduced to the sport of final approach slalom trying to avoid going up the jacksy of a 152 or traumahawk (good excercise for the thighs though). Still it shouldn't take more than three to five hours (some places have a minimum of five before they sign you off) to get the hang of it.
