If I connect the Micro SD card to the ICSP header, do I have full use of all of the digital pins for other functions? I'm afraid the ICSP header may be hard wired to some of the digital pins.

Looks like the SPI interface uses 4 digital I/O lines Arduino Playground - Spi for details
But remember you can add other SPI devices to the SPI bus so more than 1 device will "re-use" the data lines.
Looks a sweet module
