I honestly wouldn't worry about it. You laid out the reason for learning guitar: you want to play some of your favorite songs. That is pretty much where I am at. And in terms of who learns what in what time frame, who cares?

I don't think there is anything to gain by keeping a scorecard. Enjoy the instrument and take what you want from it.

Edit: barre chords. Some are harder than others, and when I am faced with one, I usually use a "cheater chord". A few whiskeys and we all sound the same anyway.
