For the latching plastic, I'd recommend buying headers with it build in. The original proto boards used Molex KK series connectors.

Will do, thanks for the heads up - I see the extra 16 DIO lines are multiplexed (in function) with PWM/I2C/SPI functions. The KK series are nice but only friction-locking (I think). I might go one step further and use latching polarized connectors.
