Lol sure. I'm not much above noob status myself lol.
Download supersu from the market if you haven't already
Get the TWRP image for here:
http://teamw.in/project/twrp2/249
Download the Rashr app and open it. Allow super user permissions.
Select the recovery option, it's the second one down, after kernel.
Select other from storage (you haven't flashed a recovery yet so it'd not in the history.
Navigate to the file where you have the TWRP image and select it. It's probably in your downloads folder
And that's it. It should just take a few seconds to install. This app gives you the option to reboot into recovery, so you can immediately check to see if it worked
