Meadowhall, Apple Store is really friendly (like most of them), they might offer a cleaning solution that can really work that yellow off, they might use the same solution that they use to clean the iPhone's before applying the screen protectors. Traditionally, I've heard of cleaning solution pens that are used to get rid of yellow and dirt off the keyboard.
Oh and you can install Lion on your laptop, you'll just need to bypass the Intel Core 2 Duo, i5, i7 blah blah screen. Hit up Macrumors for a guide, there's one similar on there right now which is quite popular because it's used to get Mountain Lion Developer Previews on the older hardware.
Also, chasethebase I love your deviantArt ;-)
