You might not need the reset button (or the ISCP port, if you plan to program it externally), but you probably will need the 10K pullup resistor.

Otherwise the RAS pin will float, and could reset randomly.

+1. The pullups essential. To be honest I hate resistive resets, I always use a reset IC.

The reset switch is used to reset the microprocessor, either simply to restart the program or to clear a software fault
