Hey there, Paul!
If the drive is so severely damaged, cloning the data from it is definitely not a good idea! The easy way would be using a cloning/migrating software for the apps but it will clone the corrupted files/sectors as well.
The best thing to do is to backup or copy/paste somewhere else the data. As for the programs, since you will be reinstalling the OS on an SSD, it would be best to reinstall the programs and software apps as well. Otherwise you are risking potential issues with the compatibility and proper loading & running of the programs. It might not be the easiest way to do this, but it's always best to start from scratch when you are updating any hardware on your system.
Hope I was helpful!
