The thing missing from your drivetrain specification so far is the sprocket. What is it, and have you mounted it the right way round? You hub doesn't need to be touched, it should give a chainline of between about 41mm and 43 mm depending on the sprocket. Have you checked the frame alignment? That could f-up your chainline too. Really, something is wrong somewhere if you're trying to get the chainring so close to the stays on a steel bike. My fat stayed aluminium track frame (no dimples or bends in the chainstay) will take a >57T ring without any trouble.
