Presumably you are listening to jazz music...if not, that is the place to start. Include both the stuff that you hear and are drawn to, as well as listening to some internet 'feeds'...for example, Pandora has some presets that are good, but you can also type in an artist's name and hear that artist mixed with others that are stylistically similar. Listen to saxophone, trumpet, guitar, as well as clarinet. Initially, I would urge you to listen to a broad range...e.g. Dixieland, Klezmer, Choro, American Songbook, Bebop, Cool, and include some modern artists in the jazz fusion space...e.g. Fourplay and other projects by Jeff Lorber and his friends (favorites of mine). My favorite modern clarinet player is Anat Cohen, who is a virtuoso but plays a broad spectrum of music.
At some point, start including playing along with 'whatever is playing'...try to hear musical lines and then play them against the music. You can use Aebersold recordings or other playalongs, but I like just listening to the radio...particularly Jazz Fusion and Jazz Funk which has a lot of variety.
Your Buffet tradition will take you far. The only thing that I might recommend if I were your instruction, is to get an alternative mouthpiece setup that lets you use a softer reed...your M13 with a #4 Aria is not extreme, but 'in the pocket' for tonal stability and polite sound. For example, #3 Vandoren V12 or Legere #3 Signature with a mouthpiece like a Grabner K14, Portnoy BP02, Fobes 3L, etc...none of these choices is extreme, but rather 'in the pocket' for a different range of expressive freedom. The list is long and everybody has their preference, but a tip opening of 1.05-1.10mm and a facing length of 17-18mm will open up your options for tonal/pitch flexibility.
I used to play an R13, and ended up playing more folk music and big band than anything else, and switched to large bore Selmers. I do sit in with a community orchestra (if I pay attention to pitch stability), however, with this setup and have no problem blending, but I can also fill the melody space in a bluegrass or country band.
