I don't think you're having any problems unstuffing the Stuffit archive 
– the Disk Copy 4.2 images aren't going to be exactly 800k – 824k 
sounds about right.

Once you get those files to a IIGS the only program that I know that 
will convert them to real disks is Sheppy's DiskMaker 
http://www.sheppyware.net/apple-ii-software/diskmaker.html

But, that's going to be more effort than it's worth. Once you've got 
the Unstuffed Disk Copy 4.2 images, use ADFS to convert them into 
2images, which any emulator can use.

ADFS is an OLD program that I still use that works much like CiderPress 
for handling disk images, although it's not as feature rich. From ADFS, 
open the disk image you want to convert from the Disk Copy 4.2 format. 
Select it from the ADFS 'Desktop' window. Go to the ADFS's pull down 
menu 'Disk' and choose 'Sector Order and Format...'. That's a slightly 
quicker way of changing between Disk Copy and 2image format.

Hopefully then you'll have working 2images that are a bit easier to deal with.
