Fenneken will be a Fire/Fairy type.
Chespin will be a Grass/Ground type. (Who would have guessed.)
Froakie will be a Water/Dark type.
In order to get Pangoro, you have to level up Pancham to level 32 with an another dark type on your team. So, I was suggest you get Froakie. You can catch Pancham in the first forest in the game. In the first route you can catch Fletchling and 1 other pokemon (I forgot what it was).
I saw a video on corro corro and saw the guy who was player in X and Y. He had Honedge at level 32. So, you might get a Honedge in mid game.
You can get Clauncher and Skrelp on route 13 by fishing. Clauncher is X exclusive and Skrelp is Y exclusive. Clauncher and Skrelp reach their full evolve at level 30 - 36. (Forgot what level)
So, here is some stuff for X and Y, hope it helped.
Post your team below for X and Y so far. Here's mine; Pangoro, Talonflame, Clauncher, Honedge, and not sure about the next 2 pokemon.
