I got a 2.8" inch TFT LCD TOUCH SCREEN and i want to use the same arduino to control leds but i can't because the lcd takes all the pins(its type of shield), what are the important pins of the lcd so i could connect the important ones and the others i will use for leds,
Here's a pinout 
i'll be happy if someone would help me in making my project
You have a regular "Blue 2.8 inch Mcufriend" shield. It just happens to be white!
The Touch pins are normally on A1, A2, 6, 7 or 8, 9
The display should work with the MCUFRIEND_kbv library from the Library Manager.
The Calibration sketch from the examples will identify the correct pins.

So which pins I should connect and which not? So I could use the pins that ain't connected for another things
You MUST connect 5V, 3.3V, GND. And 2-9, A0-A4 for the LCD. (i.e. the pins marked LCD_xx)
You can use any other pins e.g. 10-13, A5. I do not advise 0,1 because Serial uses them.
