So I won a Ritchey crankset on ebay a few months ago that I am planning on using on my fixed gear project. It is a road frame conversion with an 68mm BB shell and horizontal dropouts. Below is a link to an identical crankset (except I only paid $37 for mine- I had no idea I had gotten such a good deal!):

I am using a Formula rear hub with a chainline of 42mm. I just bought a 46 tooth track ring that I would like to mount on the outside of the crankarm spider and I am wondering if I buy a ISIS bottom bracket with the right length spindle this might be possible. I have used the search function and read Sheldon's take, but I still can't figure things out. How do I know what bottom bracket to buy? What other measuremnts do I need to know? Or is it not possible to get a 42mm (or thereabouts) chainline on the outside of the crankarm spider on a road frame?
Many thanks.
Edit: Looks like the BB may be Octolink. I don't know the difference and I don't know if this changes anything.
