Like Naurdor said, LOOT is a good idea (Loot Order Optimization Tool), it can be found here. It is a small tool that essentially checks a database of known mods and tells you whether there could be any conflicts, and it can be made to automatically reorganize your load order. I think it plugs into Nexus Mod Manager as well (but I use it separately and it works pretty well). Note: it may give 'errors' for certain files, because some mods aren't 'cleaned up' properly. Don't worry about that, the mods aren't broken, just a bit sloppily written or edited.
