Hi Spencer,
Typically the bandwidth is set at 10-20% of the sample rate; I usually use 200 Hz sample rate and 40 or 50 Hz bandwidth with good results, but the choice does depend on the application. Yes, the signals are analog until converted to digital by the ASIC.
All 6- and 9-axis motion sensors are the same this way, they read one sensor at a time ASFAIK. However, you can have the data loaded into the FIFO at a fixed rate and then burst read the FIFO; this is a way to have the data time stamped but it isn't really representative of when the analog sensor experienced the signal, rather when the digitized data was loaded into the FIFO. Still, this can work for a lot of applications.
I'm afraid I don't have much more to offer.

I have a few questions related to sample rates:
If you have any insight based on your experience or from the literature it would be super helpful.
