Just be careful going down this rabbit hole. Modded Oblivion is an incredible game. But it's very easy to get so obsessed with modding it to perfection that by the time you get around to playing it, you're kind of tired of it all. I did this in the last couple of months, probably spent 20 hours trying to learn how to mod it, and quit playing after two. (Keep in mind I've probably invested 200-300 hours in it in the past, so it's not like I've never played it before or anything.)
Plus, modding Oblivion has actually gotten harder than it used to be (when I say used to be I mean many years ago last time I played it heavily) with the introduction of Wyre Bash. I understand all the awesome things Bash/BAIN does, but it seems like everywhere you go to try to learn how to use it just says, "There's no such thing as a quick guide to Wyre Bash. You just have to use it to learn it." and that is not fun. And everywhere also makes sure you know that Wyre Bash is incredibly hard to use, but super awesome. Yah, that's pretty intimidating.
