Well isn't the visa you got last May still valid? They are normally multiple entry and last 10 years. Why do you need another one?
The coaching job maybe - do you need a different type? If so you are back to square 1. You could also be turned down for the job on the same grounds BTW.
And what sort of coaching job? If it's a proper paid one rather than a student exchange I doubt if you would get a visa anyway, criminal record or not. US working visas are next to impossible to get for UK citizens.
I'd say your chances are slim - but you can only tell for certain by paying your $100 or whatever to find out.
