Can this be installed on a Toshiba Satellite A505-S6980? Plus how do I "duplicate" the entire contents of my HDD to this new SSD?
The interface is: Serial ATA [SATA]

Yes. I bought a $12 enclosure for my old laptop drive and used it as a USB device. That way I can copy whatever files I want back onto the laptop and use the old drive as a backup as well. You will need to use you recovery disks or a set of windows disks to load on your new drive. You cannot copy programs only files.
