Two hopefully easy questions?

Hi Ed,
If you look at the datasheet you'll find that on the 18F1320 you select if a pin should be analog or digital thru ADCON1 (see section 17.2), so to set all pins as digital you can simply do ADCON1 = 255. That's one command.

It's also a good idea to look at the initialization conditions (Table 4.3), there you'll see that ADCON1 defaults to a value of 0 on power on and reset which means that all analog pins starts up in analog mode so you need to switch them to digital.

You can use Darrels AllDigital but it's always nice to be able to do it "manually" in case AllDigital isn't kept up to date or doesn't work for whatever reason.
