Simpliciti clocks on CC430 and UART

Im trying to hone my baud rate down on a UART port to 57600. I using a an EM430 with simpliciti 1.1.1   The system I connect to says the current rate is 59210. So my question is what is the best way to hone that I mess with the DCOCLKDIV  and hence the SMCLK which is what my UART is sourced to ....or do I play with UCA0BR  or UCBRS or UCBRF...... I dont want to mess anything up for Simpliciti...


Any thought out there???
