Sterilizing bottles and paci’s?

Sooooo FTM here, 35 weeks and nesting! and I’m wondering if somebody can give me some info on sterilizing? I have a small countertop sterilizer, babebay brand? I have a bunch of pacifiers from our shower, all different sizes. When sterilizing, should I only be doing the 0-3mo pacifiers? Then sterilize the later month ones down the road? Or should I just sterilize them all right away? I don’t know much about the process so I’m not sure when to go about sterilizing them.
