Rush the pyramids. It is a lot of culture, and you'll get early doubling, too. Then use the palace to prebuild. You won't be wasting turns building nothing, you'll be starting your next wonder.
If your palace prebuild will complete before learning col/philosophy/literature, learn literature first. If you are researching fast enough to slingshot and then learn literature before your prebuild completes, then slingshot first.
I'd go Pyramids.
