Support races this year are Ferrari Challenge (a.k.a. Ferrari Crashfest) and the Le Mans Legend race with cars between 1949-1965. No idea about how their sessions fit in the schedule.
Personally, I'll only be able to watch Wednesday practice and a bit of qualifying from home. Leaving Thursday morning... and going to the race. SO EXCITED.

As for streaming: http://www.lemans-tv.com/ will have some onboards during the race, Speed TV will carry the race in the USA, and in Europe the race is going to be viewable online on Eurosport Player (with a subscription fee for one month though).
