So here's the links for things mentioned in the videos (the sidebar I mentioned is to your right as we speak).
Get Rikaichan at this site. You will need to download its dictionary separately. I also use the names dictionary. Usually shift switches on the fly between dictionaries and kanji details.
You can join Lang-8 here.
Download Anki here.
You can download many kinds of Anki decks here.
The audio links I mentioned are here.
Firefox search engines can be found at Mycroft.
Bonus for ya: All the 1kyu grammar terms are explained in my own poor words here. A few 2kyu grammar explanations can be found here And my general advice for taking the JLPT can be seen here.
A great way to have Firefox with you wherever you go is to use the USB-drive version from Portableapps.
