As you mentioned, sax music has to be transposed to match with guitar and bass. But since you're probably going to be learning by yourself for now, don't worry about it yet! Practice scales and arpeggios, since that will help immensely with jazz improvisation.
Once you're feeling comfortable, you can pick up a fake book (like this one), and it does the transposing for you. There's a few hundred songs in each one, and there are books available for instruments in C (like guitar), bass clef (like bass), Bb (clarinet or tenor sax), and Eb (alto sax).
When you start transposing on the fly, take the key signature the rest of the group is playing in, and add 3 sharps. If they're playing in A, you're playing in F#. If they're in G, you're in E. A lot of times, playing with guitars puts the sax in terrible keys with loads of sharps. Practice your scales.
There is a trick to transposing sheet music on the fly. You still have to mentally add the 3 sharps to the key signature. And then move every note down one full line or space. It takes practice, but eventually will become easy. Helps to practice your scales.
