Integrating accelerometer output

[gnormhurst]

Can you tell me how you integrate faster than 38 Hz? Do you use a timer interrupt, or do you count fast cycles and look at the gyro every so many of those?

You use a timer.
It is important that the time interval between samples is accurate.

Timer interrupts, definitely. You need to keep your timing very stable in order for things to work right.
