First I'd look for a ready made box, like the types used to enclose thermostats, meters, valves, etc., and customize it to hold the camera and, if necessary, flash. I'd try the Grainger or other industrial supply catalog. If I couldn't find something ready made to modify I'd build one using Lexan, acrylic or plexiglas.
To trigger my D2H/SB-800 I'd use a Pocket Wizard. Other cameras can be triggered from a reasonable distance using an IR remote. I've heard of some D70 owners using inexpensive universal remotes (for TVs, DVD players, VCRs, etc.) to trigger their cameras remotely. Pretty cool and a helluva lot cheaper than a Pocket Wizard (which also requires an expensive adapter for the D2H and other cameras).
The tricky bit would be mounting it where it wouldn't endanger the players, interfere with the action or damage the wall or supports, unless you are given permission to drill into a concrete wall. If you are the official photogapher for a school they might be willing to accomodate such a request. At the schools where I shoot I'd have to homebrew a support, such as suspending the camera enclosure from the ceiling and taping it to the wall to keep it stable. There's no other way to mount it short of drilling into the wall. I'd rather just crouch under the basket for closeups and hope nobody runs over me.
Some venues accomodate cameras mounted directly over the basket. These can make for dramatic shots. SI and other sporting mag photographers do this routinely. You'd need permission and a clamp to attach your gear to the overhead supports. Getting permission might involve consulting with the school engineer - most colleges have such a department on campus. High schools and below might have an engineer available for consultation, or one assigned to the entire school district. Pro and semi-pro venues may already have accomodations set up for photographers, including flash, and you'll just need permission to use their setups. However there's probably a waiting list and applications may need to be submitted well in advance of the season. Even tho' I live only 15 minutes from Texas Motor Speedway and know someone who works there I have yet to get a press pass because I haven't submitted an application in time.
For volleyball you could ask permission to set up a tripod at the side of the net. Balls and players seldom go off course directly to the side, so it's unlikely the camera would cause any problems. At the schools where I shoot the first row of seats are only a few feet from the sideline, so I'd want to arrive early enough to set up before someone claimed those seats. And, of course, be sure it's okay with the school officials, game officials and coaches.
Track would be the easiest to set up for remotes. You could set up a tripod behind the fence or use a clamp to attach to the fence. Bogen/Manfrotto and others sell 'em. Ditto auto races and other such events.
