Get the Bb Real Book The Real Book (B Flat, Sixth edition). It's got the melody and the changes. You should have it anyway. Now that Spotify is in the US and you can collaborate playlist with your friends I use it for practicing with at home. I compiled the following Spotify playlist from the list of standards in Aebersold's Vol 1. Most of these are in the Real book.
Blues Lines - Jazz Blue Lines
Jazz Ballads - Jazz Ballads
Jazz Waltzes - Jazz Waltzes

What I've been working on for our Friday jams - Friday's Jam List
I started with Freddie Freeloader, Killer Joe(I put it on wikifonia), Satin Doll, Song For My Father, Misty, Blue Monk, All Blues. Pretty much anything that wasn't too notey and medium paced. Jamming is great and glad to hear you're doing it. It's nice to hear you've got a clarinet in there as well.
