Q: 

Multi-variable indexes in postgres

Im looking at an application where I will be doing quite a few SELECTs where I am trying to find column_a = x AND column_b = y. Is the correct to create that index that something like the following?

CREATE INDEX index_name ON table (column_a, column_b)

Yes.
