I'm with [MENTION=408183]cdmurphy[/MENTION]; tubes and tires and you're done. Unless you want to pony up for some much, much lighter new carbon fibre bike, you're not going to get a significant gain anywhere else. Unless your current wheel sets are real boat anchors. An extra 40 miles/week in the saddle will be your best investment, by far.
Don't be one of those guys who thinks some new gear is going to be all the difference.
