Luis, that stuff is always the worst.
Happens to me every time a new champ comes out!
As for lanes, it doesn't matter ALL that much until you hit a higher tier of play (probably after level 25 or so). At a certain point, playing to as much efficiency as you can decides games. At low levels, being dumb and over/underestimating champions and a differing scale of item knowledge decides games.
