Hey Ibarrett, unfortunately MB is a bit confusing at first, because it gives you access to its hefty suite of functionality right from the start!
if you are adding a Digital Media release, please put in a link (under 'external links' in the first page when you're adding it) to where you got it from, eg iTunes or Bandcamp. A CD that you've ripped to digital yourself or downloaded doesn't count, it's still a CD release.
currently it's a bit confusing because you've added a digital media release but your edit comment says "From jewel case with cardboard cover purchased at concert." which isn't a digital media source. Just ask if this is unclear in any way.
the digital media release is the only one that has a barcode, but that's presumably from the CD you have in hand? If so, the barcode should go on the CD release, digital media often doesn't have one (well, that can actually get complicated, but for the sake of clarity, we most often leave it blank on digital media release)
as you can see from the artist page http://musicbrainz.org/artist/2dc9595f-dbe1-4bb2-88d4-da3979db77cd
there are now multiple 'release groups' for that album. You can merge them all by clicking on them and hitting 'merge' (jesus2099 is already merging two, the yellow highlighted ones). It makes everything much clearer and easier to use when we keep the different versions of the same release grouped together like this
don't be afraid to just keeping going back and editing them until you've got it right! I'll subscribe to your edits and can always lend a hand. Keep it up!
Sorry about making you read all that, but hopefully it's helpful!
