I find "The TSR Archive" very useful also: http://www.flash.net/~brenfrow/index.htm It's got less information than the Aceum, but bigger pictures. 

Wulf Ratbane said:low levels (1st to 4th):
Keep on the Borderlands (could take quite a while and net quite a few levels)
mid levels (4th to 7th):
the Slaver series (A1-A4)
The high level stuff is the easiest--
Lost Caverns of Tsojcanth (if you need a filler in the 8th level range)
Against the Giants
Descent to the Depths of the Earth
Vault of the Drow
Queen of the Demonweb Pits
