Yes, they are nearly identical in outer diameter, only a 0.1" difference.
Tools like these are quite useful when comparing tire sizes:

As for camber, it depends on what you mean by "a lot".
Compared to a completely stock car that has -0.5* to -1.0*, then yes.
Compared to a car that has an alignment catered towards track driving, then no, it's about average.
Compared to a hellaflush car which can anywhere between -3* to -10* and up, then no, it's quite tame.
To put it in perspective, the wheel doesn't "look" like it has excessive camber at -3*, however, you will be able to see it in the contact patch and tire wear.
If it's your daily driver and you're racking up thousands of miles per year, you may want to consider a less aggressive wheel size for better tire wear / life.
