I don't know if it is the same everywhere, but W's are not even looked at here with regard to your GPA. I was told by my counselor that they don't pay a lot of attention to them these days because of the increased number of students returning to college who have families and other situations... The majority of students applying aren't necessarily 18 and 19 any more
I don't have much to add regarding your second question except to speak to your academic advisor and see what he/she suggests. I definitely wouldn't assume that you won't be accepted into the program... go have a talk with them and see what your options are.
I wish you the best of luck!
