Stock Video Workflow

Hey all,
I'm trying to get into selling stock video and I'm not sure what the best/fastest way to get footage from camera to site is.
my current workflow is to shoot in 1080 59.97p xavc-s, import to FCPX for key-wording, trimming, and naming, then export the selection from the browser with a custom compressor preset (50Mbs h.264, .MOV, no audio) and then upload to the sites.

Is this the best workflow?
Is 60p the best frame-rate for stock?
Is there any way to batch export selections from the browse?

I would love to hear from anyone else who shoots stock and uses FCPX about their workflow,
Thanks in advance for any help.
