My spotlight recently got hosed, this is a good reference on how to fix that.

I had this problem turn up the other day. Rather annoying, but a simple Terminal command will take care of it. "sudo chflags hidden /private" (the /private is the folder you want hidden).

defaults write com.apple.iTunes allow-half-stars -bool TRUE ----- This simple Terminal trick turns on half-star ratings in iTunes. Slick.

Create a script that will have a custom song play from iTunes when mail from certain users arrive.
