Wheels and tyres are often a good place to start if you want bring the weight down a bit. Not only do you have to drag the weight of your wheels up hills, you also have to spin them around, which soaks up more energy the heavier they are. So you benefit from every gram saved on the wheels/tyres works in more than one way.
A carbon fork could also bring the weight down quite a bit, and in addition improve the ride quality (in my experience, carbon forks ride better than steel ones, and carbon vs alu forks are no match at all)
