So, I recently lost a my entire mp3 player's library of music and I need to start collecting again.. right now what I'm looking for are albums or collections of orchestral versions of game music. Any games are cool, but RPGs are vastly preferred.

An example of what I'm out for would be "Drammatica - The Best of Yoko Shimomura".

Not sure how many of the links are still alive, but have a search through GoronMoron's thread here (Thread 39734) even if just for some names.

You've probably got most of them anyway, but just a quick list from memory:
Game Music Concerts 1-5
FF Concerts (20020220, More Friends)
Hyrule Symphony + Majora's Mask Orchestrations
Gyakuten Saiban Meets Orchestra (2 Versions)
DQ Concerts + Symphonic Suites
FF Orchestrations (Grand Finale, Fithos Wecos Lucos Vinosec, Dear Friends)

Besides that, just search through GH. Also, look at some Series/Composer megathreads; if orchestrations exist, they'll typically have them.
