I going to west Edmonton mall. which rides and shops are best?

Hi, i am 11 and i am going to West Edmonton mall for the first time. i am going from July 23rd _26th, possibly th twenty seventh. i am going on the water park and the amusement park, and i am going shopping, too. Witch rides are the best? i am going on the mind bender, but what other rides are really fun? And which stores are really good for clothes, and are fairly cheap, cuz i only have $300.00 to spend on stuff. Please help!!!!
