As long as her output of wet and poopy diapers is normal and her weight gain is on track, there's no reason to be concerned about rapid feedings. As babies grow, they become more efficient feeders, and by the time most babies are a few months old they can get a full feeding in 5-10 minutes at the breast.
Offering a paci is a very personal choice. At this point, use of a paci is probably not going to impact breastfeeding, since the major danger with early use of a paci is that it will screw up your baby's latch. The only thing you might want to think about is how you feel about using a paci in the long term. Some moms prefer to limit paci use because they don't want their kids getting hooked on them, and it can be easier to never use a paci than to try to break a kid's habit.
