fishface: http://www.sheldonbrown.com/chainline.html is the most he has on it. there are some blanks you'll have to sort out. gear (cog) spacers won't do the job, as you're likely 10mm+ too far center. You have to basically move the axle spacers from the right side to the left moving the hub over to the right. there's a picture showing the bits on that site, with a blurb.
In the image below, imagine that your gear (cog) is on the left side (backwards).
If you wanted to move the hub (and the gear/cog) over to the left (also backwards), you'd theoritically move some of the axle spacers from the left side to the right side, effectively shifting the whole hub unit to the left.
again this image is showing most of the spacers on the left, which is not what your hub looks like. This is the final product you want. You'll be starting with most of the spacers on the right and you want to move them left. Just imagine what i'm saying and flip the image, and replace all the lefts with rights, etc...
of course this will then move the rim over also, leaving your wheel off center.
to fix this, you then need to dish the wheel back over. DIshing is accomplished by losening one side of spokes, two or three turns and tightening the other side by the same amount. You need a wheel truing stand to have it done well.
Honestly it's really dead simple and can be done in about 10-15 minutes with experienced hands. It might take you a couple hours, assuming you have the tools and the patience to figure it out with fucking anything up royally.
