Let's see...you pretty much got it right, first catalogs featured each girl with accessories, school items (dress, lunch, books), Christmas items (dress, doll, gifts for Samantha of music box and stocking and box from Dad for Molly and St. Lucia tray/wreath for Kirsten), and the nighttime items.
Yes, Samantha has always had her gingerbread house.
Kirsten's quilt was originally sold by itself and the quilt kit was available with the Party Treats when it was first introduced. For some reason they combined the two things to make a new item.
It seems like the desks and new outfits came out in 1990 or 1991 and I think those were the first "new" items added to the collection since the summer and winter items. I think they might have come out around the same time as Felicity too.
