presuming ur going to control AC , better to use an opto-isolator between the gate and uC .and power control by delayed triggering (u'll need a zero crossing detector part)

2.) how can i interface wireless control system ( e.g. in remote control car) with 89c51? which kind of modulation is required ?

option depends on excat requirement.
