From the serial number placement it's either a 91 or 92. Probably a Quantum Road, although if it's got a long wheelbase it could be a Performance touring model.
That font started in 1992, but since it's a repaint that doesn't mean much.
Can't help with the bottom bracket and spindle issue, but Phill Wood would be a good place to start. I'd appreciate hearing your results.
