Good choice. I just bought one a few weeks back.

Buy this! 2 batteries with slightly larger capacity than stock... Great deal...

Build this! Buy the Monopod on Amazon for $9.99, Tripod mount for $5.80
The Battery BacPac is a good one from what I hear as well (no experience with that yet)

32 Gb Class 10 Micro SD card
+1 on the wifi killing the battery life.
