Marc,
As a couple others have mentioned _ undercabinet lightning! That is the biggest regret I have had people mention after their kitchen is done, they were sorry they didn't spend the extra $$ for undercabinet lights. Since it is still early enough in your project, consider having the electrician prewire for them, even if you don't install them right away. I don't believe you will be sorry, they make such a great inprovment in not only the countertop lighting, but the overall look of the kitchen.
One thing to remember, if your going to have granite counter tops, the granite acts just like a mirror, you will be able to see the undercabinet lights reflected in the granite, so you probably don't want cheap florescents or rope lighting. I did one once and they used rope lighting and strung it all over the bottom of the upper cabinets. The reflected view of the lights looked like an aerial view of the LA highway system at night. The halogen or quartz strips don't look bad at all.
If you really want to showcase it, have the electrician put a few switch controlled plugs over the upper cabinets for accent lighting, that way you can simply plug in accent lights over the cabinets. My wife loves hers, she uses white rope lights most of the time, at Halloween she changes to orange, and Christmas it is usually red or blue depending on how she decorates. Really makes a heck of an impression on people that see it, so much so I have had people want to add them (undercabinet as well as overcabinet) to their kitchen. Doesn't do much for me, but keeps my electrician happy.
