Ok, to solve 99% of the sorting problems there is a program called BOSS. Be sure to grab both the executable and the latest masterlist update (they are on the same download page). When you start BOSS (you can run it from inside Wrye Bash, there is a button to the bottom left) it will sort every mod you have to the correct loading order. If you still have problems, Wrye Bash has a "Mod Checker" function, that is near the BOSS button, bottom left. It will list missing files and other errors. Remember this, because it is a really useful function. Unfortunately Oblivion may be a bit hard at the beginning with mods, because there are many things to watch out, but don't worry! There are just a few recurring problems that you will avoid quickly in the future, don't get discouraged :)
