Re: blown in insulation
Sprucey pretty much summed it up with regardes to the weight --- shouldn't be a problem.

Cellulose insulation doesn't really loose too much R value when it settles in a horizontal configuration such as in an attic --- settlement is factored into it's R value. The whole settling issue was more from vertical configurations such as blown into walls --- the settling could create a void at the top of the walls leaving a small area of little to no insulation because of settling. However, for some years now many blown celluose installations are done with a dense pack technique which minimizes settling issues for the most part.
In a nut shell with insulation more is better.
