Anyusernameopen,
before you say anything about the Vilna Gaon and his lack of understand, you MUST be very careful for your Olam HaBa. His main student said when he dies that he was 100 days from being on the level of RITVA. If you do not understand the greatness of that statement, please learn Shas a few times with Rashi and Tos without Artscroll.
