I second your lesson suggestion. I was lucky enough to have lessons, and was very happy I did.
That said, if one can't do the lessons, I fully suggest working through some of the adult learner workbooks - the ones for immigrants. Some are more grammar-heavy than others. The draw is twofold: You learn some common speaking terms plus you get introduced to grammar, complete with exercises.
