This is a super easy repair. Takes about 10-15 minutes to install the bumper, tops. But, it also looks like you have damaged your fender liners (or perhaps that was a pre-existing condition). Many people run without fender liners, but I think they are worth having, and they aren't terribly expensive to replace either.
Otherwise, if you curbed a wheel hard enough to deflate the tire, there's a good chance the wheel itself is bent and your alignment is off. Definitely worth looking into once you get all the bodywork behind you.
