RMarkwald's suggestion is a great way to go, especially if you only need a short-term hookup. You won't need to worry about getting the proper size enclosure. If you plan on leaving it attached long-term, an enclosure will provide more protection for it.
Your drive is SATA and 2.5". Your laptop specs say it shipped with a 500GB drive, so it probably isn't a "slim" one (you can measure it; the thickness is usually stated in millimeters). Some enclosures will hold only a slim drive, so check the enclosure specs for the maximum thickness drive that will fit.
There's heavy competition for dirt cheap enclosures, and the quality varies. Some have a high percentage that are DOA. Amazon is a good source and they have a big selection. More important, they have reviews. Pick an enclosure with a low percentage of bad reviews.
As far as difficulty, I'm not familiar with your specific model, but on most laptops, the hard drive sits in an accessible compartment with a cover. The cover either slides off or is held closed with a screw. The drive just sits inside, plugged into a connector (it generally isn't fastened in). Once you remove the drive, you either plug the USB adapter onto its connector or install it in an enclosure. The enclosures are just a case with a connector at one end that you plug the drive into. So installation is basically following instructions to open the case, plug in the drive, and close the case (the case is usually held together with a few screws).
