Do you want a show piece or a driver? If the latter, just get some replacement floor pannels, fix what needs fixed, and enjoy.
If you are going for a complete restoration, you will likely find a lot more rust to deal with and may indeed want a new tub. The investment at that point will almost always be more than one can recover by selling. Sometime way more.
