Dont:
Take phone calls and spend a lot of time with texting and email. Same goes for miscellaneous internet/social media stuff.
Unless arrangements have been made, don’t leave early. This is your gig, and it needs your full attention.
Get into the politics of the situation. Many musicians have lost gigs by getting into the middle of things like other people’s pay, gig arrangements, etc. This needs to be discussed privately, not at rehearsal.
Show off and overplay. Again, only other players of your instrument would care, and they don’t usually hire you.
Do:
Be positive and pleasant. This is a professional situation; check all your problems at the door, and devote your full attention to the gig. You will get more work by being laid-back and friendly.
Have all your stuff set up for the downbeat. If you are a drummer or keyboard player, this means showing up earlier so you are not scrambling to get ready. We all know that singers and others don’t have the same setup needs… That’s just how it goes. 
Write things down on the chart or in your notes. You will likely forget them if you don’t. This attention to detail will make life easier for you and the group. 
Be helpful, but avoid constant suggestions and opinions; this becomes a disruption. You are part of a team. 
Play at an appropriate volume. There is such a thing as “rehearsal volume.” sometimes at a full run-through, you can crank up, but when learning and discussing the music, avoid blasting. And, by all means don’t get offended if asked to turn down.
