Also, there are various 3D printers out there - plus the opensource reprap/makerbot ideas.

For quick turnarounds of simpler parts, though, FirstCut with HDPE or Nylon is hard to beat.

Safety / Emissions Compliance

Generally speaking, all electronics products have to meet EMC/EMI (emissions and emmunity) tests for sale. In addition, products with any "high voltage" components are required to meet safety tests.

In the US, the "UL" or equivalent mark is required.
For Europe, testing to meet the CE requirements is needed.

Medical DeviceLink has a nice summary of the key international standards:

For North America, the FCC Part 47 and UL standards apply. Specifically, there is no immunity requiremens for NorAm.

Cortex M3 bringup

When bringing up the Cortex M3 (the Luminary chip on the board), we'll need a compiler/linker toolchain. IAR's is nice, but expensive. It turns out that CodeSourcery has G++ products, including a lite version -- the following blog mentions the process nicely:
