You've received some great answers so far. I'm going to go ahead and add my little bit of info...

1. The chicks were just hatched a couple of days ago. One of the three is not hatched yet. They are quite active, moving around, etc. but we have not seen Mom paying too much attention. Are we supposed to be feeding these little guys or does Mom take care of this for awhile? I did see on another site that Mom regurgitates food for them for awhile but we have no idea for sure if it is being done. If we are supposed to feed them, how, and what? The chicks seem so fragile and we do not want to harm them or do something wrong, so could I get some input as to just what we should do.
Sounds to me like mum is feeding them. As already stated, if mum/dad wasn't feeding the chicks, they'd be dead by now. You will want to only check the nest box twice a day. No more then that. I usually check in the morning and at night. Try to do it when the parents are out of the nest box. Quakers can be nervous parents sometimes and if you mess with the nest box too much, they'll abandon, or kill, the chicks.
So for the first 10 to 14 days, leave the babies alone with the parents. You should be offering the parents LOTS of soft foods. Cooked brown rice, whole wheat pasta, lots of cooked veggies (the ones that are safe), basically anything that is on the softer side. This is great food for them, and thus the babies.
During this next 2 weeks, start doing some research. There isn't many Quaker breeding/weaning articles out there, so look for Cockatiel articles. They are pretty much the same when it comes to raising them. Research is SO important (as I'm sure you've discovered). Raising parrots is much, much different then cats/dogs. It is quite a bit more work.

2. If we decide not to hand feed them, what is the advantage and disadvantage? Do we take them from the Mother or what? When? What do they eat?
The advantage to handfeeding is that you'll have much more tame chicks. Quakers that are parent fed rarely make good pets. They tend to be mean and bitey and take a LOT of work to tame them down. So if you want to have pets out of these babies, then you'll have to handfeed them.
Usually chicks are pulled between 10 and 14 days. They need to be fed 5 times a day and the usual schedule is: 7 am, 11 pm, 3 pm, 7 pm, 11 pm. This is just a rough guide. Basically, so long as you are feeing every 4 hours it's good. You don't feed through the night at this age, as this let time for the crop to completely empty (which it should do at least once every 24 hour period).
Parrot handfeeding formula is what is fed. You can buy it at most pet stores in the bird section. Roudybush, Kaytee, Hagens, they are all good brands of formula. Mix it up according to the instructions on the bag. It is very important to have two thermometers to test the temperature of the formula. Too hot and you could burn the chicks crop, too cold and you could cause crop issues.
You'll also need a brooder, heat source, syringes (or a bent spoon whichever method you chose to handfeed), and the list goes on.
Handfeeding parrots is tough work. They are very time demanding and if you do one thing wrong, you could kill the chicks.
Here are a few articles that cover handfeeding. They are for Cockatiels, but the basics are still the same:

You should have lots of videos pop up and that will give you an idea as to how to go about it. Here is one of NCVon's videos (she's a member on this forum who had to handfeed one of her Quakers from day 1...not an easy task

):

Another option is to start looking for a breeder in your area and see if they would be interested in taking the birds from you and let them handfeed the babies. Some breeders would do this for a small fee, or if you don't want to keep the birds, then you could just give them the chicks. That is something to think about.
