Lydia doesn't even know how to use her powers yet. The tree was a pay-off. It shows that the whole Banshee idea with Lydia wasn't an after-thought. Banshees sense when death is approaching, so that's how Stiles knew the parents were being sacrificed at the tree. So yeah, it also allowed Stiles to know where Jennifer had the parents.

As for the surrogate sacrifices, I agree that it was just lazy writing for the most part but not as lazy as the whole "OMG EVERYTHING IN THIS SEASON THUS FAR WAS ALL PETER'S PLAN" scenario just for 3b. In the end, you can still reason that without it, they wouldn't have known where the tree was and that Jennifer didn't know that there were already surrogate sacrifices, so she still wanted to kill them.

Also, why did she need Derek as a guardian? To fight Deucalion? And what would sacrificing the parents have done?
