Beetle questions

Question 1:
In my application I have a transmit and a receive Beetle. I ported the S/W I have developed on an UNO to the TX Beetle in 10 minutes and it works perfectly.
When I came to porting my RX code I discovered a challenge. I use PIN2 on UNO as an interrupt pin. According to the Leonardo data sheet I could use 0, 1, 2, 3 or 7 . My options on the Beetle are 1, 2 or 3. I assume 2 or 3 is the best choice to not compromise the USB connection. I don't need I2C. Is that correct?
Shame to use this pin though. I put a header on one of the Beetles to easily prototype and this will be messy.
Question 2:
Without the benefit of a schematic, are the 2 pins labeled '+' and '-' connected to each other? Can they both be used to power the device?
Question 3:
The Wicki mentions the power voltage <8v. I would like to power my TX Beetle from a 2S li-ion which may reach 8.2v. Big problem? OK? Worth a try but don't blame you?
Thanks
