@SailorJerry - First, congratulations and good luck with your new baby! Everyone has different experiences with pacifiers. I use a Nuk pacifier that I started at about two weeks and I haven't had any problems. I have a nice, fat, healthy breastfed baby.
It's definitely best to wait a couple of weeks if you can manage it so that baby is breastfeeding nicely before you introduce it. (But I know people who started in the hospital and it was no problem for them.) Some babies, especially breastfeed babies, won't take a pacifier at all, while others love them.
Besides nipple confusion, a controversy with them is that some people think they can cause parents to not learn their baby's cues, to just stick the paci in their mouths and be done with it. So if you do use it, make sure to try other ways to soothe your baby first.
Another problem some people have is that their baby will be so soothed by the paci, s/he won't eat. I would not use a pacifier with a baby who wasn't meeting weight gain goals--for instance, a baby that hadn't regained birth weight by two weeks.
