What to order for my daft table ?

Hi all again OK IM thinking :-? I have 25 squares if lets say I buy the arduino mega when I get to set this up with 25 separate leads, can the set up be easier then getting Arduino Duemilanove, can I run say 25 separate run offs from the mega, the mega not a lot more and if I don't get for some reason to finish the project I can use the mega for other protects, the led's as for the brightness I don't no what mcd brightness to get, the red led will have to show good threw the black glass day and night so if someone can give me a link for the led what they think will be ok say on eBay, or a supplier with paypal as IM in the UK and payment is easier,going to be a bit cheeky here if you give me the like resister and anything else I will have to get with the led mcd ill order, I've ordered the Shifty VU Shield that's one thing out of the way for later.
All help as I say is appreciated from all, dare I say thanks to me team, ha ha :)Tricky :slight_smile:
