[SodeSceriobia]

Shaykh Riyadh ul Haqs teaching of Bukhari is aimed at the laymen he gives these to the public so I doubt there's a prerequisite to do other Hadith books first. As mentioned he almost always gives the opinion of and within all four madhabs. Also, his English is better than most other speakers.

Not sure how many of his recorded Bukhari lessons are online but you can purchase them (the lessons must be numbering into over a thousand now) or listen free every Friday via their al-kauther website.
