LED Audio Spectrum Analyzer HELP Needed!

[Xevious809]

I'm slightly new to circuitry and I'm designing a 30x20 (30 Wide, 20 High) LED matrix for this project and I really have no clue what materials I need to make this possible.
I will obviously be multiplexing the lights and am not sure if I should, and by what dimensions, break up the matrix to make it easier to apply to my arduino. (Someone suggested 30x8, 30x8 and 30x4)
I don't know what circuitry components I need, or the resistance needed for the cathode and anode ends of the LED Matrix (LED info down at bottom).
Any direction or guidance for the matrix and even the end product, the audio spectrum analyzer, would be greatly appreciated.

5v Input ~>

LED: 5mm blue
3.0-3.4v / 24mA max / 13,000 mcd

Whatever makes it the brightest without burning up is preferable.

Thanks

Multiplexing LEDs causes each LED to have current only for a moment. Then the average LED current is low which produces low brightness. For normal brightness then the peak LED current must be much higher but we do not know what is the maximum allowed peak current and duration for your LEDs.
