Default INA217 DRV134 Opamp bypass caps

What is the purpose for an opamp between INA217 and DRV134? The output of INA217 appears to be in line with input of DRV134. Also.....What is the best cap for power legs. TI shows .1uF. I currently have a .1uF ceramic installed. I have seen others use .1uF, .47uF, 1uF and even 10uF. I recall someone suggesting wima caps. I have to place a digikey order soon and would like to get appropriate caps.
