Nothing special, straight wire for serial from PIC to PIC, maybe an inline 100ohm resistor for protection (no real need for a MAX232 or the like unless you get crazy with distance), straight wires for power and ground...
Past the receiver PIC, it's standard wiring from PIC to LCD.
If you can make a PIC and an LCD work, you can do this easily.
Just try to remember not to shoot yourself in the foot...small steps...get blinky working, get the LCD working, get 2 PICs working, get some serial going between the two, tie it all together.
