VCOM max current draw and LED- wiring of the display DT070BTFT-PTS1

This is my first time wiring a TFT display and I have some questions about the display DT070BTFT-PTS1 :

What is the maximum current draw from the display VCOM input supply ?
Should LED- (pins 31 and 32) be connected to GND ?
Should we provide external resistor to limit the current of the backlight LEDs ?
Is it OK if my PSU 9.6V is shared between AVDD supply and VL (= 'LED+' - 'LED-')

Thanks in advance,
