I've ran parts of it, and I ended up turning the GM'ing for that campaign (I moved) to one of the players and he finished it out in 3rd edition.
ENworld's creature repository (the name escapes me) has conversions for all the monsters in it into 3rd edition stats. I'm sure a Google search will turn it up.
The rest is pretty easy. Once you have stats for the monsters, the rest should be a no-brainer.
