Usually for layouts they recommend joists (1x4s usually) every 16". That might be overkill unless you are one of the people who believes you need to build it strong enough to walk on. I think 24" centers is okay if you aren't going to walk on it, as long as you are using the plywood you specified. But 48" spacing... wow, that is quite a gap.
