For interfacing LCD you can use our LCD library. Check the following link for that.
Interfacing LCD with PIC Microcontroller – Hi-Tech C
For relay interfacing coding is very simple. It is similar to controlling an LED. But in hardware you need to use a relay driver like ULN2803 IC or a simple transistor. Please refer the following link for that.
Interfacing Relay with PIC Microcontroller – MikroC Pro
You can easily code it for Hi-Tech C as the coding is very simple.
