    That's the controller. Who made the LCD screen is not as important as who made the controller, as you need to figure out how to interface with the controller. The controller takes data (parallel in this case) and uses it to drive the LCD segments accordingly.

    It prob a voltage regulator, LCD's tend to be fussy about power.

    The extra chip will be a DC-DC converter, as many graphic LCDs like yours require a relatively large negative voltage for the LCD drive. You should find a schematic on using that IC, and feed the output from it into the LCD drive on the LCD module via a 10k pot to adjust the contrast.
