Page 1 of advice needed

hi therei need some advice
i have just bought a multi region phillips dvd 958
and i want to know if it wll play RCE encoded discs?
also it has got a built in 5.1 decoder and all the connections now what kind of amp do i need for surround sound? will a six channel do
also would i be able to wire my hi fi into the amp and use its speakers and could i wire anything else into it ie sky ,playstation 2 etc .are amps switchable between devices . I know nothing(much) about amplifiers so any advice would be greatly appreciated
thanks
