Check out this page: http://www.geeetech.com/wiki/index.php/3.2TFT_LCDYou can find schematics there on how to hookup display straight to arduino, no shield between. Worked for me.Someone said that if you connect Led-a pin from display to digital pin in arduino instead of 5v pin, you're able to control display backlight. Command can be found in Hennings utft library manual. But haven't tested this.
You could try clearing EEEPROM, maybe that will help.http://arduino.cc/en/Tutorial/EEPROMClear
The RTC module...SDA --> pin 20, SCL --> pin 21
