Check out Eric Cressey's articles,
here's one, for example. He works a lot with Mike Robertson, one of the co-authors of that TNation article above. Apparently he is THE shoulder guy among the new wave of strength coaches. Not only is he very extensively published (in legitimate, peer-reviewed journals) but he also has a 295 deadlift at 82 kg bodyweight...
He does "e-coaching" but it's pretty expensive. If you have insurance I'd go with a competent physio shoulder specialist, as others have mentioned.
