here is like a crash course in advanced calc
these helped me a little bit when i was doing advanced calc (though i suppose you're doing some kind of prerequisite to advanced calc).
try a google search for "advanced calculus" or whatever your class is called.
you may also want to try the MIT OpenCourseware website. they often have video lectures for courses as well as course materials.
there are a lot of things in the topics you mentioned. maybe if you took them one at a time and expound on your difficulties, we would be able to help more
what text are you using?
