Answer 1

Now that the ethernet is working, let's reinstall Network Manager. It comes in a few versions so we'll have to do some guesswork. Please open the terminal and do:

sudo apt-get update
sudo apt-get install network-manager

See if you can then start it:

sudo service network-manager start

Post any errors or warnings.

I think the link you posted for wireless is probably correct.
