What size/width slot is required for pushing the plastic edge into?

Not sure what width you are asking about. If you are talking about the channel it goes into it is pretty much standard size which is a groove you press the flange into. The only width/gap you need to make sure of is the door to the frame which is about 5/8. Close your door and measure the spacing. I used this to replace the original of 37 years old and it fit like a charm. Very satisfied, looks good and will stop any air leaks. Hope this helps.

The groove you press the flange into should be installed first, because regular doors do not have it, right?

Actually our door had a groove and we just replaced the old stripping that the cats had shredded. Easy and worked great
