Man... I'm still looking for my first 7, I'll be over the moon if I can score a deal anywhere near as good as yours.
About the middle pressure plate, I don't use Flyd Rses anymore, but when I had my RG, I removed all three pressure plates as I found them to be a hinderance more than a big help. Especially if you are going to be gigging, you don't want to have to stuff around replacing strings.
When you string that puppy up, if the strings are correctly fitted/wound on the machine slots, you'll find you won't need those pain in the ass lock nuts... however, if you want them... they are a dime a dozen from any good guitar store.
