I think the best idea for surge protection is a whole house surge protector. I do recommend a UPS for the projector though as if the power goes out while your watching anything, you want to be able to turn the projector off and let it go through it's normal power down/cool down.
I learned about a Power Bridge from this forum and was able to run the projector off the UPS in my equipment rack.
