MatthewPapa's GameWarden site has the actual files but he asks people to sign up so that they can reserve a place in a queue to stop everyone downloading the game at once.
The link is directly below his post.
As for the version of freespace you have I think you probably could install FS2_Open on it and have it work reasonably well. What you actually have is a copy of Freespace : Colossus no doubt. This is basically a cut down copy of FS2 with working multiplayer and the first 10 missions.
The .exe files are different but you replace those with the FS2_Open .exe files anyway.
However you'd probably have problems playing mods on a FS2_Open/Colossus hybrid so eventually you'd want to upgrade to the ISOs.
Don't bother with the HotU version. For you this would actually be a retrograde step as Colossus is much closer to being a full version than HotU is.
