After all, in many cases, the changes in the monsters are pretty minor. It's not going to hurt the adventure at all if the kobolds have the wrong skill distribution, or if the hill giant's hit points are off by 5 or 10.
Now, there are some monsters that have changed a lot more than that, certainly, so you'll want to compare the stat blocks in the module to 3.5 sources. But honestly, unless you see major differences, I wouldn't worry about updating at all.
I agree. For the most part you can run 3E adventures off the shelf. As long you aren't concerned with everything lining up perfectly (I doubt John Cooper would do this), the changes won't be noticed.
There are a few exceptions, most deal with tactic used by NPCs. For example, often mid-high level spell caster statblocks assumed they were casting various Bear's Endurance spells on themselves in the morning and had them on all day. That doesn't quite work in 3.5, but can be worked around sometimes.
Psionics is another exception. The rules just changed so much, they usually require an major update.
