It doesn't seem like you even know what you want. Everyone seems to be telling you to do this and that. What do you want? Are you happy with the guitar? Or, since you just hear that you should upgrade this or that, you want to? Use your own judgement, not someone else's.
You say your a beginner as well. Most beginner's don't know what they want and alot of them will not even notice small changes. Keep the guitar the way it is for a couple years. Once you get into bands or start finding what kind of music you really get into, then change stuff as needed, not because someone said you should do this or that.
