First off, Don't be embarrassed to be a beginner. Every time I learn a new song, I am a beginner too. So you've come to the right place. When you look at the song list You'll notice Guitar symbols next to the songs. 5 guitars is the hardest. I recommend starting with songs that are 1-2 guitars. Breaking the Law, Livin' after midnight etc. If it were as easy as just looking at the tab and playing it, Everyone would be able to do it. And since everyone can't that ought to tell you something. You need to build some skills before you can fly across the neck like Angus. Learn how to bend notes to the correct pitch, how to hold the pick, how to alternate pick Etc. Etc. Etc. As with everything there is technique and finesse. These come with practice. You will get them if you work at it. Go through the core program and if you want to play songs too, then start with the easy songs so as to not overwhelm yourself. Take your time and be patient. Believe it or not if you spend a little more time now it will go faster later. Don't try and be Angus over night. It ain't gonna happen and you could hurt yourself. No Kidding you really could! Yes We did all learn stupid stuff like Jingle Bells at some point. And ya know what? Next Christmas it just might get you a little love under the mistletoe. So don't knock it. One of the First songs I ever learned was the Theme Song for the TV show Green Acres.....30 years later I'm still workin' on it. I'm an established, working guitarist who gets paid to play. I can play all those songs you listed damn near note for note. The Key part there is "Damn Near" and that my friend is why I am here. To continually learn and to better my skills. Music is a wonderful thing. There is always something new to learn around every corner. Be diligent and practice daily and I promise before you know it, you too will shake it all night long.
