Skyrim mods?

Hey guys, I owned Skyrim for the 360 and saw it on sale today for PC, so I decided to buy it since I have extra cash just laying around. My issue is that I am still relatively new to PC gaming (built this machine about a year ago) and I haven't really modded any games besides games that needed fixes (Dark Souls). I really don't know how to mod but I just want to know if there are any extra programs I need in order to get mods to work? Been seeing a lot of "load order" and I have no idea what they hell that means nor how to do it. I have looked up if I need any auxiliary programs and nothing shows up, I don't know if that means there are none or I just suck at looking things up on the internet. But any help will be appreciated, even if it is just a point in a direction.
