You would be best served taking a couple of semesters of IMMERSION at your local college/community college. You can't learn without any foundation. Those CDs, tapes and books are for people who at least have a basic knowledge of the language and can go from there. But if you have trouble conjugating verbs, lack vocabulary, etc... you're going to be better off taking college courses. Two INTENSIVE courses are usually enough to get a basic conversational understanding.
