In general, only have one mod installed in a folder at a time and don't try to launch any other mod than. Also key to note, very few mods are made to be compatible with each other, the few exceptions being one such as AOTR and 2.02 (yes, the unofficial 2.02 patch is a mod).
Installing the mod is simple but not completely straightforward, if you go through the steps carefully you should be fine.
