Do I need to wash these before using?

I would. I used the Medela steaming bags that you can get to clean the equipment. I don't steam the bottles any more though, they seemed to crack.

Are these compatible with the Freestyle?

I have the pump in style, but I believe all the accessories can be used between all Medela pumps so you should be fine

Will these fit the Spectra S1?

These will fit the narrow neck flanges (medela and spectra compatible), but not the wide neck flanges that come with the spectra pump. I actually prefer the medela valves over the spectra duckbills, so i use the narrow neck flanges with the spectra pump. There is a long backflow protector you can buy.
