John -

As far as serial versus USB, you will find that majority of potential users prefer USB (laptops, etc.).

Many of the "new Arduino style" boards have UART for serial (5-line implementation) with usage of USB-UART cables.
Sparkfun is one group that sells these (their version of the standard FTDI cable offering at $20).

The 18-pin daughterboard you referenced uses the FTDI FT232Rx chip (L version is 28-pin SSOP; Q version is 32-pin QFN)

I like the FTDI FT-232R --- due to its ability to be programmed (invert the serial line, etc.).  Saves chips for those needs.
