You can keep alternating the latch between both sides too. Let baby latch on the side with more milk first, so that the thirst and hunger will be filled, then change sides, so that the breast will be stimulated to increase milk production. Also check your nipples to make sure that they are clean and the openings are not blocked by dirt:)
Yes. I just let the performing one work harder to compensate for the other one.
Try power pumping on the slackier boob
