Not sure what is the desired setup, but lets assume you want use internal default configuration (I am unable to locate eeprom and unable to see SMBus connected). Then you want to set CFG SEL register to 00. This is done by connecting SEL0 and SEL1 to ground using 100K resistors (not 36k). (if you want to set either of the SEL bit to 1, you must use 10k resistor to 3V3.
The same for NON_REM register bits 0 and 1. If you want to set 00 to the register, use 100k resistor connecting pins REM0 and REM1 to GND.
If you want to use SMBus to modify registers, you need to use 10k resistors pulling SMBUS signals DATA and CLK up. Then CFG_SEL0 is high and that means SMBus slave configuration.
Based on a quick look, there are default Vendor id and Product id values. This means that you should be fine using the internal default configuration. If you have a Vendor ID of your own, then you of course need to use SMbus or eeprom.
