Very low power operation

I'm trying to implement a very low power 08M (solar powered PIR activated garden light). I have taken my lead from this old thread in the main but also using SLEEP. I'm unclear on a couple of points:

1. I'm using ADC so I'm switching off the ADC module when not in use (poke ADCON0 register, poke $1f,value; bit0 of value is 0). Does the ADC need switching on again - presumably bit0 = 1 - or does READADC achieve that implicitly?

2. When SLEEP is used, what happens to active outputs? Do they stay as they were or something else?

Background: I will use the 31kHz clock speed and DISABLEBOD to reduce power consumption. I think I'm clear about both of those.
Thanks,
Derek
