Protein intake & weight loss

Now, I know this question has been asked to death, but I'm wondering if anyone can tell me if I'm taking a good approach to things. I'm a 21 year old female, 5'11", 175ish lbs and a collegiate athlete who's trying to get back into shape after ankle reconstruction last summer. I've been vegan for almost 3 years now and am mostly happy with how I feel with those eating habits, but after tracking my calories I've noticed my protein intake is really very low, especially considering I'm an athlete who needs to maintain, if not add to, my muscle mass. I'm currently trying to lose a bit of extra weight, so not add any muscle at the moment. In the past three or four days, I more than doubled my protein intake (to 90-100g/day) with a combination of whole foods and supplemental (vegan) protein shakes. 
I'm wondering a couple of things. First, as I'm still trying to heal my ankle while simultaneously train for the fall season, will increased protein be beneficial to that healing process? Is it a bad idea to up the intake so suddenly? And finally, will the increased protein really change much at all?
