If everything in the brake system is working properly, adjusted properly and free of air, then before I spent a lot of money on hardware changes I would do some research and try a different set of pads. I have an old manual brake Corvette that I restored and the pads I put on it grabbed very well and stopped the car easily. But after awhile it suffered leaking brake seals and in the process I changed the calipers for rebuilt ones and they came with new pads. The new pads were noticeably less aggressive and pedal pressure was higher to stop quickly.

I don't have a pad recommendation but it's much cheaper to try a different compound pad than to try new rotors and calipers - especially since options on the Jag in-board brakes are somewhat limited and usually expensive.
