Well, I don't have Oblivion installed since my old drive died, so... why don't you just use what people posted at TME? I have my data files directory backed up somewhere, I guess...
All right, since I'm nice:
Book Jackets Oblivion - Adds high-res, unique book covers to all books.
Book Placing - Allows you to rotate books to properly put them on shelves. Not actually that useful.
BTMod v220 - Sexy interface mode. I think we all already use it. I also use the *dark* version, which is just *awesome*.
Better Wine - Wine bottle retextures.
Cyrodilic Brandy - New mesh/texture for the brandy.
DLCs - Yes, I have all the official mods.
Fishclub - It's a fish, but it's a club. Fuck yeah.
Illuminated Within Reborn - Or revamped or re-something. Files just say IWR. Anyway, it's the one that makes the houses turn lights on and off at various times of the day. Completely great.
Kart Passive Beasts - Something to chill out the wildlife (I don't like fighting dogs and bears and junk). I heavily modified it for my own purposes, though, as the original mod was sort of stupid.
Level Slow - Comes in a variety of flavors that let you slow down how fast you level. I'm using the 3x longer version.
Natural Habitat by Max Tael - This guy has done some great stuff, but it's all just a little bit too buggy for me. Including this. It adds birds and bugs that fly around, and they're really great, but they spawn "wrong." Like in the cities you'll find that too many bugs spawn, and in the same places. If I could figure out how to edit that out, it'd be great, but I can't. Otherwise it's awesome.
NoLoad - Get rid of little streaming loading message.
Potion Sorter - Renames all the potions and sorts them in logical ways. I think I stopped using this out of fear that it would screw up future official mods or something, but I don't remember. It's still good.
At Home Alchemy - Not a perfect mod, but it basically allows you to do alchemy without having the gear in your inventory. Just use it and it glows, bringing up the interface when you hit the mortar and pestle. If you want to pick them up, just do it in sneak mode. The bugs revolve around anyone seeing you use the items thinking you're a thief, even if they're your own.
Weather Inside v1.2 - Lets you hear weather indoors. Immersive.
Younger Hotter NPCs v1.0 - Horrible name, good mod. Just makes the chicks less ugly. It isn't extreme in particular. Just makes people look less haggard.
