In the meaning of 'zuerst' (first), 'erstmal' structures a sequence of actions. It often stands in the middle of the sentence, after the conjugated verb, to mark the first step in a chain.
Wir gehen erstmal einkaufen und kochen dann gemeinsam.
We'll go shopping first and then cook together.
'Erstmal' can also mean 'for the moment' or 'for the time being'. It expresses that a situation or action is finished or sufficient for the moment.

We've worked enough for today; that's it for now.

Erst and erstmal can both mark an action as the first step. Erst works well with a clearly stated subsequent sequence. Erstmal focuses more on the immediate beginning and often leaves what happens afterward open. These are tendencies; in the right context, both are possible.
