Nanci--re: fitting another bottle cage on the frame. You might try putting the pump behind the seat tube--looks like you've got some room there--and then you may have the space for a bottle cage on the front of the seat tube, up high to avoid the downtube water bottle. This is the setup I have on my bike, which has a small (sub 19") frame and it works quite well. I can also attach a third bottle cage under the downtube if I need it--I have an extreme fear of running out of water.
