Jessica,
I have an 1802 and the Tower but I don't have the Accessory cards that goes with that set of attachments. However, you can find a Manual for Kenmore Attachments in a free pdf here:

That document is for a much earlier box of attachments than the set you have. However, many of the feet will be recognizable and it will help you get started identifying and using the attachments you have. I have another box of attachments with accessory cards (but not the set from the 1802) that I could scan but a lot of it is duplicated in the document I linked. If there are attachments you can't identify, you could post a picture and ask about it and I'm sure someone can explain it. Youtube is also a good source for demonstrations for many things sewing related, including attachments. So if you can name it and search, someone has probably uploaded a video about it.
Good luck.
John
