Actually, I have worked a lot with that particular LCD driver, in serial/SPI mode, on a HCS12 project. So feel free to ask me any questions about it. The most important thing is to set both CPOL and CPHA in the SPI or you may get hard-to-detect clock skew issues.
But I won't send you any code, because (1) it is your job to write that code and (2) the copyright of the code I have written belongs to the company I work at.
