First off welcome to the forum. My advice to you is read all the threads and do searches for your questions. All the things you have asked has been discussed in great detail. You will even find the firmware update and how to install as well as the SD card size requirement and the method to format the SD card before use to install the firmware. If worse comes to worse just ask and we will either give you the thread location or respond to your question. When you get a chance post pics of your setup in the gallery and once again welcome.
