No, I don't think you'll need any patches, froggy.
Given that you have Homm3 complete, can I recommend at some stage you look for the "Middle-Earth_Allies" map by Jean-Francois Beaudoin? If you like Lotr, it is an amazing map - when you get the hang of it, try playing it as Elves on impossibe. To be honest, it's about all I play with Homm nowadays - periodically, I just load it up and enjoy computer gaming at its finest. It's a small zip, so I can e-mail it to you if you can't find it.
