I will start with safeties, because having solid safeties is critical. I am not sure whether SJSU is a safety or not. Your guidance counselor should know better than I do. You need to make sure that your safeties really are safeties, and that you are happy with your safeties.
I thought that the various universities of California did not care about your freshman year grades. I also am not sure whether Stanford cares about Freshman year grades. Freshman year will be less important pretty much anywhere. This might help you.
Stanford would be a reach or a high reach. I might be tempted to add it to the list anyway (and no, it is not “an Ivy”, but it is superb for math and CS).
