Ryan,

I took a quick look at the datasheet.  It all looks pretty straightforward to me.  It says the the device can either have data clocked into via an external clock (synchronous) or using an internal clock (asynchronous).  You only need to worry about setting the internal clock speed if you want to use an asynchronous serial data stream. That's like normal RS-232 style communications.  Ignore that.  Just provide the clock yourself via the SCLK pin.  You just need to set a bit on the SX to either high or low, and then provide a low to high transition on the SCLK pin via an SX output pin.  Lather, rinse, repeat.  Just keep setting your bit value followed by a low to high transition until you've transferred all your bits.

Thanks,
PeterM
