You get more memory and can buy more games if you do
Yes. But be aware that not all updates are necessary. Some of the recent movies actually have the necessary updates installed onto them and will install the updates into your player if necessary
A graphic card takes the data necessary to display images on the monitor, processes it, posts it to the monitor and then continues to update it as necessary.
If your player has WiFi, you can get the update just by connecting to the network. If your player doesn't have WiFi, then you need to download the update from the player's manufacturer's website, burn it onto a blank disk and then put it into your player. Some of the most recent movies might contain the necessary updates on the disk and if necessary, it will update your player on its own (that happened to my family)
