"Atomic Edition" just means the full game with the fourth episode, like Doom vs "Ultimate Doom." The expansions all came in the Megaton Edition, which was pulled when Gearbox released the 20th Anniversary, which contains the new World Tour episode. The 3D models you saw were probably the High Resolution Pack, or HRP, which is a mod.

Your best bet for playing Duke is to go into the MEGA link in the Retro FPS thread and download the game and its expansions (I think they also have World Tour's episode in there too). After getting it, run it in the EDuke32 source port (though there's more ports now since the old days, so you should consider doing some legwork to see which ones have the features you most like).
