I think the best thing is to establish a routine. It's especially important at bedtime to help them start to calm down. So, for example, dinner, quiet play, bath, potty, brush teeth, read 1-2 short books, tuck in, maybe a quiet lullaby after you dim the lights, then a good night/sleep tight sort of sign-off. Do the same thing every night - you change up the books and maybe the song, but not the order of things. For toothbrushing, use an egg timer (the hourglass type with sand, not kitchen timer) or sing the ABC song (once) or Happy Birthday (twice) to measure the proper duration.
Handwashing - make up a little song so they rub the soap and don't just put it on their hands and rinse it right off. You can find lots of songs for basic functions on line or sometimes in DVDs from the children's library. Ask the children's librarian for suggestions and don't be afraid to order from other libraries in the network (pick up and drop off at your branch - very convenient).
Read books on these things, which show kids in the story doing the stuff you want your kids to learn - how fun it is to help set the table or sweep the floor, manners, that sort of thing.
I say no no NO to electronics! It's too passive, and it just becomes an impossible habit to break. You will regret tying your children to devices, for many reasons. Mostly, if you teach them that this is how you learn, they will demand their own devices from a very young age! You really want to teach them (and model for them) the value and rich traditions in books and libraries. "Managing points"? Do you mean a virtual sticker chart? Why not do a real sticker chart? You can find very inexpensive options at teacher supply sites.
Also, institute a combination lost & found bucket and "job jar" - depending on the age of the kids. Lost stuff (or stuff left in the middle of the kitchen floor) gets tossed into a big bucket (look for a wicker basket if you care about looks, or a sturdy plastic laundry basket or galvanized tub from the container store. No organizing or separate tubs for different kids. All misplaced stuff goes in there - backpacks, single shoes, lunch boxes, Hot Wheels cars, and so on. Yes, it's a pain to dig through and find their missing stuff - and that's the point. It would have saved them time to put it away to begin with. As they get older, you can put a bunch of job "sticks" there - use oversized craft sticks like big popsicle sticks and either write words or put a photo or magazine pic on it (great for pre-reading kids). Or use construction paper/poster board and then laminate it. You can find some cute poems on line which basically say, "Lost something? Do a job and earn it back." So if they want their toy back, they can put out water for the dog or clean the litter box or empty the trash first. Upgrade the difficulty as they get older. Be sure these are age-appropriate tasks and start small. No sending a 3 year old out to walk the dog or having them clean the litter box, right?
Laundry: get a small laundry basket for each child, color coded. Even the smallest child can match socks (make it a game!) and fold stuff that doesn't matter if it's wrinkled (pajamas, underwear), and place them in the basket belonging to the appropriate person. They fold/sort for everyone (not just their own stuff) and put in the basket - they learn that everyone works together. Then they take their own baskets to their own rooms and put their own stuff away. If you can find a way to store/stack their things at kid height, great. Look into simple and inexpensive closet storage for kids - bins for socks, hooks for belts and hats, etc. Easier than dresser drawers.
Consider a towel rack on the back of each bedroom door - a place for wet bath towels other than the bed or the floor. Put a small hamper or a duplicate of their small laundry basket in the closet for dirty clothes - that keeps off the floor.
Don't be afraid to have a child go without something because they didn't take care of it. That special shirt they wanted to wear to school? Oh well, it was on the floor under the bed. "How unfortunate for you, Susie, that you didn't put it in the hamper where it belongs." They take lunch in a paper bag because they didn't clean the spilled food out of the lunch box? "How unfortunate for you, Billy." They can't go to the park because Mom and Dad had to clear the table and feed the dog? "How unfortunate for you guys. Now there's no time."
A good way to discourage waste is to start good recycling habits and buying habits early on. Things like no straws and no juice boxes, but instead using reusable stainless steel water bottles. Specifically saying, "No straw, please" when ordering in a restaurant. Making your own single-serving snacks in reusable containers instead of buying little snack bags that get tossed. Use reusable grocery bags and put the kids in charge of flattening them and putting them back in the car before the next trip. Play a game to see who remembers to take them in when you go to Target or other stores, not just the grocery store. Kids can take out the recycling too and help at the bottle/can return if you buy soda or beer that needs to go to the machine - it takes time, but let the kids keep the money they get from the 5-cent returns. Getting them to take care of the planet makes them less selfish and gets them thinking of others.
