Also, with the built in frequency multiplier can I get a stable 8Mhz (or 16)
with just a watch crystal -- enough for some high speed serial communication
via the uart/spi?
The User's Guide goes into minute detail about the available clock modules and
the clock signals derived from them (SMCLK is the one you're wanting for SPI):

Chapter 4 has all the details while fig 4-1 gives a schematic. I fail, however,
to see a frequency _multiplier_ (other than a rational number <= 1, that is) in
that schematic ...
