Thanks guys. I believe the back issue is a fit problem. I do have them over the stock mats, but removing them will cause the mats to sit lower and I actually think the weathertech mat is just slightly too large causing the ripple. As for the fronts, as long as I don't scratch the plastic, I'm not really concerned about the issue. Even if I remove the stocks, there will still be a slight overlap, so I may just leave it the way it is. Overall, the mats fit great and I'm pleased. It was raining this morning and its nice not having to worry about the floor and stock mats on the driver side and passenger side when I have someone in the car. I def recommend the weathertechs over the other options out there. They seem like them will protect the floor very well and will def do the job I bought them for. Thanks for all the input.
