Hello /vp/ this is my first time playing pokemon and I'm playing the X Version.

I have the following pokemon with me:

Quilladin level 21
Combee level 14
Zigzagoon level 16

And a lot more in the computer.

Is there anything I should know or pay attention as I play. Since I'm early in the game I don't think I've screwed it up yet.

I want people's advice instead of info on the internet that could spoil/ruin the game for me.
