Couple questions regarding Samsung bd-2550?

[Realist01]

First off, thank you all for your help.

My first question;

1. When I want to use Netflix or Pandora, do I have to hook up an ethernet cable to the back of my computer and blu-ray player? The problem is the computer is in a different room and just seems to be an inconvenience to do that. I'm not trying to complain, but we have an older computer and DSL, will I still be able to use these options? Do I have to buy a seperate ethernet cable?

2. When downloading firmware updates, I just use my usb flash drive, and then stick it in my blu-ray and the firmware automatically updates, correct? Also, I have seen a few different updates and they say to only download the newest version, will I miss out on the other updates or does it have all the updates with the newer version i.e. 2.4?

Sorry for the extensive questions here, but I want to get the most out of this blu-ray player.

Thank you so much!
