Apparently no experts are around just now, so I'll give you my two
cents worth. I'm sure the experts will chime in after they are rested
up.

It really depends on which picmicro chip you are using, but for my
case:

1) 16F819
2) only 1 analog pin needed
3) choose RA0 as the analog pin
4) choose other pins for LCD
5) study datasheet, register ADCON1 allows a mix of digital and analog
I/O pins
6) also study ADCON0

There is probably a better way, but I just set those registers
directly:

ADCON0 = 0b01_000_001
ADCON1 = 0b10_00_1110
