Sterilizing & washing baby items

What is the best way to sterilize baby items - pacifiers, bottles, etc..?

Also how the heck do I sterilize wubbanubbs? Do I only do the pacifier or is there a way to clean the whole thing?

As far as baby’s clothes, do I really only need to wash what she is going to wear in the first few weeks / months before she comes or do I just do everything? So far I’ve washed towels, washcloths, blankets, sheets, bows and newborn - 3months items, basically anything I felt like we would be using in the first month she’d be home I’ve washed so far.
