K.,
You don't want to do much of anything to train them at night. It will be a natural biproduct of them being trained in the day. If you wake up your daughter every two hours, her bladder can become trained to produce MORE urine at night and it will make the situation worse, not better. Not to mention that neither of you will get a good night's rest.
Make sure she goes potty before she goes to bed. Don't have her drink a ton just before bed. If she is thirsty give her a little water. If she is old enough to handle this, have her practice holding the potty for a little while during the day to strengthen her bladder. I even had my daughter play "stop and go" on the toilet to strengthen the muscles.
When she has reached a point where you can tell that she can wake herself up or make it through the night, talk to her about the importance of getting up to go and keeping her bed dry. This is when incentive charts come into play - when they are capable of waking up and getting up or holding it all night. Make sure the path from the bedroom to the bathroom is lit with nightlights.
Doctors won't do anything about nighttime wetting until at least age 5-7.
About the poop - if she makes the mess, she should clean it up. If it becomes a habit because it gets attention, put her zip up pajamas on backward with a safety pin if you have to, put a onesie or leotard under her nightgown or whatever you have to do to keep her from getting her clothes off. Of course, this means that you will have to help her go to the bathroom during the night, but hopefully that phase will be short lived.
Good luck,
S.
