Yes, Priiloader is VERY important to avoid unwanted updates. There is a link in my signature called 4.1u, that is the Softmod Any Wii guide. Follow that from the beginning, even if you have the items in question. Follow it to the letter, including the upgrade to 4.1, as I do not believe priiloader even works on 3.2. 4.1 is the optimum System Menu, as it was the last update to add any real effects.
