do some research on the LCD's and get one that only uses a few pins. The one that came in my package seems easy enough to use but it takes 10 or 12 pins if I remember correctly. there are others out there that need closer to 4.
I ordered a kit with my ardunio mega with the intention of doing similar. A remote display with a button to cycle through some of the data. It's sitting there waiting for me to have some time.
