There are Numbers of way to swap Models well... there is 2:
DBC:
one is BDC edits which dosn't realy work for 4.0.1, but also DBC Edits are more of a MMOwned things (just like molel edits are here, we do have DBC edits here but not near quard as much as Model edits.)
File Swap:
The other was is replaceing the files of model A with Model B and have all the files me named like Model A
but that issn't error free, some animations might be missing, likely the once related to the Motercycle and Combat mounts...
also you extract the files from the Art.mpq and finish with the latest Patch MPQ, and make sure you overwrite the files doing the collection so evey file is the lastests of it's version
I don't know what the 3rd you talking about
but i guess it's the File Swap way that you get a program to do for you.
