PIC 18F4431

Do I need to initialize the I2C command in my program? Before I do i2c_start(); I know I must initiallize LCD when using LCD. If not using the LCD, it should display on hyperterminal using RS232.

thanks

Not really.
The LCD, is handled by a separate program, and the initialisation then needs to be called in this. However the RS232, I2C, SPI etc., are handled 'internally' by the compiler, and any port initialisation is automatically done, if the #use line is present.
In general, unlike the LCD, where a command sequence has to be sent to initialise the display, the RS232, I2C etc., only need the I/O port bits setup to the right direction etc., and these are done automatically.
However the attached _device_, may need it's on initialisation, in which case, the 'right' I2C command sequence will need to be sent to perform this
