Protection packages for a new car

[digitalrain]

I'm trying to get a new 2011, keeping my fingers crossed it comes through. In the mean time while waiting, the dealership asked me if I want to protect my car with various car care packages. A friend says it's a rip off but you do want to get some of these things done. Just not at the dealership cuz they send it out and charge extra.

These are some of the packages: What is your opinion?

1: Undercoating rust perforation for under the car and behind body panels. Cost about 299$ at the dealership. protects against rust and also quietens the car from road noise...

2: Fabric protection(Lusterglaze) they have some kind of coating that makes stains easier to get out. Something like scotchguard perhaps? $299

3: UV/ paint protection(Lusterglaze) .protects against fading by UV damage from the sun. They say it's really important for red cars... $299

4: One more I can't remember now but also $299.

The total package can be done for $900

I've always had the protection package done but I was getting it at cost before. Any thoughts on what you've done and liked or perhaps regretted?

TIA
