Good feats for Incorporeal Monsters

[Thealtruistorc]

I am aware that monsters typically don't get a lot of feat support due to the fact that most sourcebooks in pathfinder are aimed towards players, but I can't help but cringe every time I see some of the feat selections for certain creatures, particularly incorporeal ones (look at the dread shadow and the Wyrmwraith and you'll see what I mean). Almost all of them have skill focus, mobility, and other feats that don't help their combat abilities in the slightest, and I want to know what some good alternatives are.

If you could rearrange the feats on your incorporeal beasties, what would you do with them?

Flyby Attack is one of the tasty ones. Incorporeal critters have a fly speed, and so qualify. Meanwhile, being able to emerge, attack, and go back underground goes wonderfully with anything that has a decent standard-action attack, especially if it's ranged.

Ghostwalk is a good resource for incorporeal monsters/characters. Of the top of my head, I believe there's a feat in there that lets ghosts use corporeal items normally.

Ghostly Grasp is from Libris Mortis. It's got a bunch of other useful stuff for undead there too, like Lifesight.
