If you like the Goodman small group recordings you might pick up their 1963 reunion album called: "Together Again!", which has wonderful sound compared to their earlier recordings.
For more Lester Young try: "Pres and Teddy", and "Lester Young with the Oscar Peterson Trio". Both albums are from the 50's and comparable to the Alladin recordings (however it should be said that some people really hate the late period playing of Young, but I'm not one of them). If you like those check out the five volumns of "Lester Young in Washington D.C., 1956". And if you don't mind scratchy recordings try "Lester Young Trio" (with Nat "King" Cole and Buddy Rich. Recorded in 1948).
For Roland Kirk "We Free Kings", "Rip, Rig, & Panic", and "Inflated Tear" are my favorites.
