I use ESPN's NBA scoreboard for following game stats and the only other place I really make a habit of checking is the NBA subreddit:
http://www.reddit.com/r/nba
r/NBA tends to have interesting/funny quotes, GIFs of key plays, the main news, etc. I often tweet stuff found on there from the Hoops account (@hoopsforum). Some of the comment threads have a few gems too.
I also read Boti's stuff when he tweets links to it.
There are obviously a range of NBA/NBL efforts from Australians like ATF, etc but I don't really read them unless I see the link on Twitter and think it will have an interesting angle or new rumour.
I don't listen to podcasts or watch video/panel shows as they're generally too slow paced. Complete nerd attitude, but with text I can skim and then get back to whatever I was doing.
