If your SSD has enough room, you can just clone your old hard drive to the SSD and run everything off the new SSD (I use Acronis True Image for cloning because it always works).
If your SSD doesn't have enough room to clone your hard drive, then the best thing to do is install everything fresh. This way you don't mess up any software configurations and everything just works.
1. Backup your hard drive and then unplug the cables from it.
2. Install your SSD in the computer and install Windows on your SSD.
3. Re-attach the cables to your hard drive.
4. Wipe the hard drive and install all your software.
5. Restore any important data files from your backup (make sure you restore them to the correct location, you have two drives now).
