In reply to Richard Carter:
I guess my first question is whether or not you use the triple as a triple at the moment - by that I mean, would you miss the granny ring on long and hilly climbs? I wouldn't worry about a compact not being 'ideal' for racing as lpts of people do race on compacts with no problem; a 50x11 is about the same size gear as a 52x12, which is a big enough gear for all but the most powerful riders.
If you stuck with the triple, i think you can use the shifters with a double chainset, you'd just need to adjust the limit screws on the front derailleur so you'd have a 'spare' click. Never done this myself but know people who have.
So I guess I haven't answered your question but hopefully it helps a little!
And have fun with the racing...its a whole other world of suffering
