If you have the equivalent knowledge of a calculus I course, then you can jump right into physics (but you should still continue to study calculus until you master single variable calc), all you need is a textbook. In the other thread, Brian C said he used Serway. I don't know much about physics textbooks but heard that the feynman lectures is superb and have found it to be a good supplement to my high-school physics class. If you can, you should try to enroll in a physics class next year so that you have someone to answer questions that you will inevitably have.
