I've gotta get me some straps, and change my fugly pedals! I suggest soaking some WD40 into the bolts that hold the chainring on, they're the only thing gripping it in place, once they're out there should be no reson for it being stuck.. Incase you're thinking of using it on your new crank, make sure they're the same BCD (spacing between the bolts) I recently found out the hard way how much it can cost buying cranks/rings and bolts seperately.. Worth upgrading the drivetrain though, make it a solid ride!
