As a writer of things C&C, I can tell you that if nothing else the Yggsburgh source material should be worth a look.
I myself penned THE CITADEL, NEWTOWN and am in the process of writing TEETH OF BARKASH NOUR and MARKETGATE SQUARE.
THE CITADEL is an urban fortress that has some good adventure hooks in it (and some downright unexpected ones as well), NEWTOWN is a village of about 1000 souls near Yggsburgh proper that has lots of mini adventures througout.
Gary Gygax, Stuart Marshall, Jon Creffield, David Smith, David Prata, Lori MacVittie, Don MacVittie and everyone else who worked on the projects have produced some top notch stuff.
As noted, you can take all of it and drop it straight in to AD&D as you like.
