Newbie level 1

Hello
I would want to have your opinion about the design of my board. My design is a analog amp for a sensor which use a 300kHz bandwidth and two voices. I have to use a FR4 4 layers PCB. I have the TOp for routing signal, the inner1 for the GND (which is a plane), the inner2 for the VCC/VEE supply rails (planes too), and the bottom layer (plane or not...?)
My question is what is the best way to reduce crosstalk beetwen my two voices ? can I place a gound plane on the top ? and for the bottom layer what should you suggest me ? in fact what is the advantge of placing a ground plane on the TOP and the bottom layers ? Is there any drawbacks to do this ?
thanks
