It sounds like you know what you want and that is the first step towards getting it! There are many fantastic schools that have bioengineering as a major. I suggest you consider which schools are feasible for you to get into based on your scores (sorry, I don't know off the top of my head what those would be). But, my point is that your school choice is probably not as important as making sure that you do well once you get into the program. And, think about where the school is located and where you're willing to go, as well as the cost of the school in making your decision.
It's hard to say what the average wage for a biomedical engineer is because there are so many possibilities for you to go in your career! That is part of why bioengineering is a good option. Generally you don't need to obtain education beyond your bachelors degree to get a good job, but if you want to be a professor you would need to get a PhD.
