Does this setup even sound correct?<p>

Yes. Since I haven't worked with external UARTs (one UART was enough for all of my projects), I can only offer this bit of advice:

Read the datasheet of the microcontroller and the UART carefully and several times.

Also, sometimes SPI isn't quite SPI. I have a '51 and a serial EEPROM, which both state they can do SPI, but since the '51 can only do 8-bit-SPI and the EEPROM expects commands of a fairly odd size (21 bits and such), I ended up bit-banging it.
