I recomend The House Of The Rising Sun. Great sounding begginer tab song.

Check out the tab first line, It's showing 4 chords Am C D and F. Now look at the first tab line itself, it's seperated into 4 boxes left to right. For each box, fret the proper chord and pick out the notes as shown.
Look for tabs that come with "chord" guidance. That way you'll have an idea of where to put your fingers and not just memorize a million unconected tab notes. The thing they don't tell you about tabs is that you really want to form chord shapes as you're picking the notes out.
One more thing. Look at the way the notes are structured for each chord. They are very similar for every chord. Makes things fairly simple.
ALso keep in mind you can just strum those chords out to get a feel for what's going on. For this song DD UUDUDU works for me. On top of that, as you're picking individual notes out, you can even add some strums in.
Have fun.
