another good thing is to make sure you camera is turned off when changing lens.

My general 'rule' of lens cleaning is to check the lenses I'm going to take with me on a shoot a day or so ahead of time...or at the last minute before I head out the door. If they look dusty or (shame on me!) fingerprinted, clean them with a rocket blower and/or lens cloth. I also take the body cap off the camera and look at the mirror. If it's dusty, maybe a single rocket blower blast. I've never checked the sensor. As mentioned above, when I start seeing dark spots on the images, I'll check for dust on the sensor and use a rocket blower there.
