David,

18F don't have banks (yay !!!), so BANKSEL is not needed

Each pin has a PORT register, intended for inputs, and a LAT for
outputs. Writing to PORT should do what you want, although not
all PORTx are bi-directional. Some are input only so it's better to
use LAT for outputs

That aside, have you set the pins as digital ? I'm not familiar with
that particular 18F but at least some need ADCON1 bits set to
make the default analogue pin digital. Others are controlled with
ANSEL/ANSELH

Have you selected an oscillator configuration and is the chip running ?

What do you have in the CONFIG statements ?

/MCLR ?

Do you have the datasheet ?
