should i get new brakes and suspension??

and honestly, i can feel it acting a little stiff and rough when driving, but maybe thats normal for avengers? they drive more sporty then soft

Well, the brake rotors look like they may soon be candidates for replacement, but only if you have other braking issues. If you don't, then just replace when the brakes need to be done. As far as the suspension, no worries there, Those parts will never need replacement due to rust. Wear of the joints would be the only indicator of need for service. The reason for replacing the rotors is also not for rust, but for wear. Rotors can be resurfaced, but personally, I don't like to do so, as they warp more easily. However, my rotors are under $ 30 each, while yours may be more expensive, justifying the cost of resurfacing, generally $10-15 each.
Or, as we northeners would say, "Rust? What rust? You ain't seen nothin' yet!"
