Clicker training is great! I have used it with Obi and he has responded well to it.
To start off with, just get your dog and a handful of treats, and click the clicker and give a treat straight away. Soon the dog will get that click=a treat.
Then at that stage you can start training with it, train something you haven't taught before, so not 'sit' or 'paw' if they know that already.
As soon as the dog starts doing the behaviour you want, click and treat, the click acts like a 'marker' so he knows that what he was doing at exactly the time you clicked was what you wanted. You need good timing
Hmm, sorry, probably not explained that very well

I'd also say get a Karen Pryor book, I started with 'Clicker Training For Dogs' which was quite good.
