I could definitely live without the Sirius satellite. All standard means is that they raise the price of the car and blend it in to look like you didn't pay extra for it. It's like my 06 to my 07 Mustang, the price went up a little. I noticed that the tire pressure monitor was suddenly "standard," but I bet that's where that extra bit of money came from.

As for the MP3 player, on my wife's 08 Avenger, she has the standard radio and it has the jack.
