Which models do I have? Can I swap accessories between models?

I'm sure this is addressed in the forum somewhere, but I cannot find it. My beloved 2008 prius finally died at 250k miles due to a spark plug insulator breaking and falling into the cylinder. I literally had zero issues with the car ever. I loved it so much that I bought a 2009 prius of the same blue color with only 60k miles. The 2008 was a mid level and the 2009 must be a base model, it's missing the backup camera, smart key, auxiliary audio input, etc.
Question 1: how can I determine which models I have (2,3,4,etc.)?
Question 2: can I transfer some of the options from the 2008 to the 2009 base model?

 

I Imputed both cars on there with the VIN, they both come up with the model: STD
They are very different models, I looked in several places on the Toyota site to see if I could find a list of accessories that came up different between the 2 cars and they all come up with the same thing. maybe I am looking in the wrong place on the site.

 

That worked..... I think. There was an option to download the full specification list, I attached the .pdf files for each. Its odd, there are more things listed on the 2009 model than the 2008, but it should be the other way around. I do not see where it mentions backup camera, smart key, etc. on the 2008 model, just generic specifications for most any Prius.
