Help with connecting Adafruit Bluefruit LE UART to Arduino Nano?

Using Arduino Microcontrollers
#1

Hi,
I'm not expert in Micro Controllers area, please help me to understand how to connect
"Adafruit Bluefruit LE UART Friend" to Arduino nano

According to Adafruit site, they are using pin :

(link for the BLE)

MOD to Pin 12
CTS to Pin 11
TXO to Pin 10
RXI to Pin 9
VIN to 5V
RTS to Pin 8
GND to GND

but pin 10, 11, 12 are busy, I'm using for SD card, and I'm using 3, 4 for GPS, what do you suggest?

SPI is a bus, usually four pins, of which three MOSI (11), MISO (12), SCLK (13) are common - you need to use a different pin for the chip select for the other device.
