Sounds like you just want to be able to play through the game in a few days and be done with it. One of the best things about Oblivion is that it seemingly never ends! You have to remember that this game came out in 2006! And was absolutely amazing for it's time. It's not perfect, but I'd say it's still one of the best games of all time. As for the main quest being too long. I think it's just right! Skyrim's main quest (and all guild quests) are waaaaaayyyyy to short. And you say it's hard to get through anything without using god mode? The game isn't that difficult. I feel like if you weren't in such a rush, you'd enjoy the game much more.

Honestly, leveling mods are good and all, but in my opinion you should play through it vanilla if it is your first time. (maybe the unofficial patch and some texture packs though) I've had some of my best memories in gaming playing through this game vanilla when I first got it. Try adding mods once you start to get tired, and want to try something different. Just my opinion :P
