I want to power this board with a 3.7V LiPo battery (due to small form factor) such as this.
Would I need a step-up DC converter or something? And where on the BBB would I connect it?

The BBB has a specific, unpopulated, header just for a single cell(3.7V) LiPo, charger and all! It sits just behind the 5VDC barrel jack, 4 pins labeled TP5-8. Page 41 of the A5A manual shows the pinout. Keep in mind that powering from a 3.7V Lipo via the battery pins will prevent the USB Host port from providing 5V power.
This guy has a small tutorial on how to wire it up: http://www.element14.com/community/community/knode/single-board_computers/next-gen_beaglebone/blog/2013/08/10/bbb--rechargeable-on-board-battery-system
Now I personally was able to power it up omitting the 10k resistor mentioned in lieu of a thermistor, where Batt+ goes to both TP5 & TP6, Batt- to TP8. The thermistor (or 10K resistor bypass) would have been between TP8 and TP7
