Getting Started Suggestions For BeagleBone Black?

I'm expecting a BeagleBone Black to arrive any day now. I'm aware of the "Getting Started" tutorials on beagleboard.org, and will certainly follow those. I am wondering if "getting started" type steps in addition to the ones posted on the tutorial pages that I should be following?

I'm not a newcomer to the BeagleBoardline, but I definitely need to build experience, and do practice, practice, practice. I also have some Gumstix boards and a Raspberry Pi Model B. I've been swimming in the smallcomputing platform sea off and on, but I've sat on the beach a lot more than I've done actual swimming (smile.)

Thanks
