I'm pretty sure I'm in the let's just be friends zone as the chick I was gaming just told me how I was like her new best friend and that she made up with her boyfriend and they're back together now. Once you've been grouped as just a friend in her mind is there anyway way to change that?

yes, but its difficult, and maybe not even necessary.
from my experience "best friend" = "fuck buddy"

if you dont care about potentially losing her and your goal is simpily to fuck her give this a try. when the boyfriend isnt around, or via text/myspace/aim/phone/ect go with the highly sexual route, act as if she doesnt have a boyfriend. if she gives you shit about having a boyfriend search 'boyfriend destroyer' on this board and use some of those techniques. the trick is to NOT be awkward, but be decently forward about your advances. also without confidence, you have nothing. trying to steal her from her man will most likely backfire, but banging her without him knowing could very well work!

a lot of guys 'change' their personalities when in this situation, so they can convey a more sexual state and the girl will in effect see a 'new' person, but that comfort the girl already has with the guy will remain.
