1) Stock struts will die a horrible death with 2" drop springs.
As well as your back and kidneys due to the bouncy ride.
Stock dampers don't have nearly enough damping capacity for the stiffer springs.
I'd highly recommend getting some dampers to match the springs before changing everything out.
2) 17X7 and 215/45/17 will work, but only on the higher offset wheels I.E. stock SVT wheels at 49mm offset.
If you go much below that offset, you're going to end up with rubbing.
A better option would be 215/40/17, especially on the 42-45mm aftermarket wheels.
Also, the 215/40 is close enough to your stock diameter, that you won't have to worry about the speedometer error.
(215/45/17 is about 1/2" taller than your stock tires)
3) Camber correction (plates up front, and bolts in the back) is kind of "vehicle" dependent.
Some need it, some don't.
At any rate, I'd at least get the rear ones, cause you'll be right at the maximum limit,
and will be wearing those rear tires rather fast if you don't get it back to around -1° to -1.5°.
