So, as has been specified multiple times here, it's best to load all this onto a totally clean 1.2.5 install.
* Download the minecraftforge zip file from the above link.
* Find your minecraft.jar in your %appdata%\Roaming\.minecraft\bin directory.
* Copy minecraft.jar file somewhere safe as a backup, i.e. minecraft-1.2.5.jar
* open up the minecraft.jar file in 7zip (or WinRAR if you paid for it, ditto WinZip)
* Remove the META-INF directory. This is standard for just about every minecraft mod there is.
* Open up Modloader-1.2.5.zip in another 7zip instance, and add ModLoader contents to the jar file. Close ModLoader zip file.
* Open up AudioMod-1.2.5.zip in another 7zip instance, and add AudioMod contents to the jar file. Close AudioMod zip file.
* Open up MinecraftForge-18.104.22.168.zip in another 7zip instance, and add MinecraftForge contents to the jar file. Close MinecraftForge zip file.
* Nearly there. Open up [1.2.5]Terraria3D-1.7.rar in another 7zip instance, navigate into the directory structure, looking for a Jars directory. enter it, and add the directory contents to the minecraft.jar file.
* In the RAR window, navigate back up to the Resources directory and open it up, you'll find a mods directory. Copy that mods directory into the %appdata%\Roaming\.minecraft\resources directory.
* Close Terraria rar file.
* Remember to check that this new minecraft.jar file must be put back into the bin directory from where you got it from.
* Last step is: start minecraft. You should have Terraria3D working, I did.
If, horror of horrors, you've messed something up with your newly minted jar file, and nothing works, your cat's climbed up your back, your three year old child has knocked the television over, yada yada, then put back the minecraft-1.2.5 jar file you saved aside earlier. It needs to go back to minecraft.jar in the bin folder. There. You can play Minecraft again. Sigh.
I hope that helps out for the moment. It seems that some stuff in 3.2.5.xxx of MinecraftForge conflicts with what was in Terraria3D, so an earlier version of Forge (22.214.171.124) will have to do.
Now it's time for me to try adding NotEnoughItems... am I a sucker for punishment or what?
Later: yup. NEI works fine. So does SinglePlayerCommands.

THANK YOU SO MUCH for this 1.2.5 workaround!!! It actually works.
This older version of forge is needed. It doesn't work with the latest.
Ok - now... why are none of the Terraria hostile mobs spawning for me? I've only seen ONE blue slime after playing for about an hour.
Wow, this one even has Adamantite, Cobalt, and Mythril(Didn't see a pic for it...?)
Either way, keep going! How about this:
Since the mod is already using Terraria textures, why not re-skin some things in a Texture pack, like the armors, and stone?
Then you could do what you need without editing Minecraft's files in your mod.
I installed the required mods and ran the game normally. But when I install Terraria 3D screen appears black.
go back a page and read the wall of text for the fix, i just did it...
Now for my own question....are there any mobs besides slimes? I never see anything else....no floating eyes, no unicorns or fairies, no antlions....nada! is there maybe a setting to change for those...or a special condition for them?
edit: i made another map after screwing around for a while and this time i didn't get any tools to start....what's going on?
Edit: nvm, i switched difficulties and now new worlds give me starting tools. also, can you turn down the corruption/hallow spread?
