Another thing...the Shimano triples have the "trim" feature for the middle chainring. It's like a smidge of an adjustment on the front derailleur. You may just need to do the smidge shift up or down on the front. This was discussed here a while back.

If you do take it into the shop, have the techs show you how to adjust it. It's super easy and a really good thing to know how to do.
Thanks Yellow! Awesome links. I think that's what it is. At least I hope that's what it is. I've got a handy tool device thingy so it's time I start using it!
