What's the right sequence for the Le Carré miniseries?

I’ve never seen or read any of the John Le Carré stories. I have three miniseries in my NetFlix queue now: (1) Tinker, Tailor, Soldier, Spy; (2) Smiley’s People; and (3) A Perfect Spy.

Are these in the right order, and am I missing any? Or should I just read them and forget the film version?

I never used to be a big fan of spy stories, but I really loved the Spooks series (MI-5 in the U.S. version)—plowed straight through them in Netflix, back to back—and looked around for more. Thought I’d give these classics a try. Any recommendations for me?

Thank you.
