Sanyo Eneloop rechargeable batteries, La Crosse BC-700 questions?

So I am in the market for rechargeable batteries, and have settled (I think) with these products:

Sanyo Eneloop AA and AAA rechargeable batteries
La Crosse BC-700 charger

1. How long is too long to leave a battery in a charger? I know the charger I am interested says "full" when a charge is complete but I am a waitress, I work 6 nights a week and do not get out of work until 2 or 3am some times. I don't want to leave the fully charged battery in the charger too long, as it would obviosuly cause problems. Does the charger automatically stop attempting to charge, when the charge is complete?

2. Are these things even worth investing in? Am I going to have to replace the batteries in a couple of years? How long do they last, typically?
