hi ved,
if the resistor array in question is being used for pullups of the uC then the SIP used is internally connected as shown in figure. U can create ur own SIP using individual resistors of the same value in a similar configuration.

Pullups are must.. there is no problem in using P0. all ports are same, the only difference is.. that.. P0 need pullups. you can use any pin you want and consider it as a normal port.... Read Compelte post
