Changing from a compact to a triple crankset...

I have a trek 1.2 (2011 model) which came with a compact crankset. I was looking to change to a triple (sora or tiagra) and was wondering would it be as simple as just changing the two cranksets or do I need to change a lot else and if so what would I need to change?

    Crankset (assuming it comes with a BB), front mech and left hand shifter I'd have thought. Can be expensive!

    (depends on what LH shifter you currently have)

    If you wanter lower gearing, then a cheaper option would be to buy a cassette with a bigger sprocket like a 28tooth.
