I have the mx900 mouse (the mouse used in both of those sets) and the 15" 1.25 ghz powerbook.
However, I opted for the apple bluetooth keyboard.
The mouse works great, (responnse time, etc), and I haven't run into any battery problems (even when I forgot to put it on the charger overnight). I only have two complaints about the mouse:
1) an off button would be nice as if I throw it in my bag, go to class, and open my laptop to use it for something not requiering the mouse (like taking notes) , as the mouse is automatucally detected, and it disables the trackpad
2) There is a little led on it that blinks when it in charging, it can be annoying.
Also, let it be known that for the charger to charge, you have to use the included ac adaptor, but the bluetooth hub is powered with the usb cable. This was a benefit for me as I didn't want to have to plug anything into my laptop (that already has bluetooth).
Another problem you may run into is the extra mouse buttons. The left bitton, right button, and the scrollwheel all work fine, the buttons directly in front and back of the scrollwheel work as if you are continuously scrolling in that direction (I use these a good deal). The remaining three buttons work with exposé, which is all I wanted them to do.
If you have any questions about the mx900 mouse or the apple keyboard, just ask
