SCT collimation is pretty straightforward - there are a few good tutorials that will help.
I like good old Rod Mollise's guide
http://skywatch.brainiac.com/collimation.pdf- this guy really knows his SCT's
Its really worth spending time getting it as right as you can - I was very surprised how much more detail you can eek out of mars, the moon, and Saturn when the scope is spot on
If you haven't already got them, I would recommend some 'bobs knobs' - these make life a lot easier.

Thing I love about SCTs, is just how easy they are to collimate, and how long the collimation seems to hold.
