You may add 1 to 2 teaspoons of sugar to each quart of water if you choose. I've never done it and I've lost very few birds over the years.
You should put newspaper over your bedding for the first day. Most instruction sheets I've read tell you to sprinkle chick starter on the newpaper as well. This is supposed to get the chicks eating on their own, as well as preventing them from eating bedding.
Personally, I would think it would teach the chicks to look below their feet for food, rather than in the feeders, and I have never done this myself. I've always just put them down on coarse pine bedding with well-stocked feeders and had great results.
Whatever you do, don't keep them on paper for more than 1 day or they could get spraddle-legged.
Just relax, read some care instructions on the hatchery sites and be calm and take your time. Your babies have been alive for at least 2 days and a few minutes more out of the brooder won't make or break them.
