Official media is 240-480p at a low bit rate. Last year (and i assume this year) you can use you teams media badge to get within 5 feet of the court to take video during your matches.
My setup last year:
2 gopros
1 cannon T3i with a 28-105mm lens IS turned on with no tripod at 28mm.
Use the field supplied recordings for the scoreboard and audio
expect to shoot 1/60 @ f3.5 @ ISO 400-800
Here is an example:

A great video by 1678 showing the courtside recording abilities:

I had lenses like the 50mm f1.4 and 70-200 f2.8 IS but never really used them. Its much better to go WIDE and film up close. A quick idea of what zooms can do what:
14: full field form the closest you can get from the stands.
28: 3/4 field from the on field position
50: close up on 1 robot form on field or half court from the stands
135-400 close up from the stands depending on your location.
Feel free to PM me with any specific questions/ setups you have in mind.
