SB bets into my straight
 

What is my move on the turn, and if raise or call, what is the plan for the river?

SB is TA-A 20/8.5/2, MP1 is TA-A 20/10/2 and Button is LA-P 70/7/.65.

You have to raise given the diamonds. Your river plan depends on who calls or reraises and what falls on the river. If you're reraised, you're prob screwed. If a diamond falls, you're probably screwed.

This is a raise.

You are raising to try to clear out any singelton diamonds, and to extract value from any that stick around.

That said you have to be prepared to dump this. I would probably call (1) back to me. Fold for two back to me.

This could make for a difficult river. If another diamond falls obviously you are done with the hand.

A non diamond would get pretty iffy. The river action is pretty much going to be dictated, by how many people called your raise, or if you got popped.
