The statues represent the "New Gods" or simply The 7. They are made up of the Father, the Mother, the Warrior, the Crone, the Smith, the Maid, and the Stranger. These Gods replaced what re known as "The Old Gods", mainly worshiped in the North by the Starks and their kin. But when the Red God Rhllor begins to amass a vast number of believers, even the New Gods are discarded among many. In some cases forcibly as you will see in season 2 as Melisandre and her like begin to burn the effigies. Expect that to happen to the wooden props you see above.
In other news, HBO execs have revealed that the next season will also be 10 episodes and that to do any more than that could "dilute the quality". They also say that they are willing to keep going with the show as long as author George RR martin is willing to keep writing! Great news, lets just hope they commit to that.
