how can i get 8 outs installed

how can i get 8 outs installed in my 2000xl

open it up and install it. Its not that hard. the manual shows you how to open it up and if you install it according to the diagram its easy as pie.

mmmmm...pie

thank you but now my question is where can i get the 8 outs?

also where could i find a case or a stand for my mpc

I couldn't personally find a place that sells them in Australia. Maybe you should search the net for a place to order from. You could pay someone to make a stand, or try making one yourself specific for your preferable position.
What you could do is get cubase or another sequencer with a software sampler and get the midi info from the mpc to the pc's sequencer then bobs your uncle, that way you can buy a cheaper soundcard.
