B5 - Horror on the Hill. It's not strictly about dragon-hunting, but the final bad guy is indeed a dragon, and there's plenty of fun goblin-hunting on the way.
O1 - Blade of Vengeance. This is all about the dragon, and is perhaps the best example I've seen from the older TSR modules. It's designed for a single player (no, it's not a solo adventure - it's for 1 DM + 1 player). Having said that, it's easily adaptable to a group and has a lot of forest/fey/elven goodness.
G3 - Hall of the Fire Giant King (part of the classic GDQ series). Could be adapted to make good ol' Brazzemal the Big Bad. Most players find him to be the ultimate opponent, anyway. Snurre (Fire Giant King) is usually one of the first few encounters, and the notorious Eclavdra (Drow Priestess) is down on level 2. But Brazzemal the Golden is unquestionably the big challenge on level 3 of the dungeon, and could even be positioned as the master behind all the giant/drow shenanigans.
