Awww, you sound like me when I first got my chicks!! Sooooo excited, but so nervous!! I wouldn't give them sugar water unless they appear really weak, it can make pasty butt worse and can give them diarrhea. People only use it if you have a really weak chick just to give them a little boost of energy to get them eating and then its a really short term suggestion, no longer than a day really.
I would just watch them (make sure you dunk each chick's beak in the water so they know where it is) and if notice any problems you can reassess the sugar water idea or give them some hardboiled egg, extra vitamins, etc.
GOOD LUCK!!! And there are plenty of folks on BYC that will answer your questions, HAVE FUN with the lil buggers!!
