Question about 2013 mod

I'm planning to play DOTP2013 modded and I have a couple of questions:
1. Do we need to extract the files from the modded .wad files or can we drop the .wad files in directly to the folder like we do with DOTP2014?
2. There's a core fixes thread with a file labeled Deck_1000_CoreFixes.wad is this different than the Deck_1999_Core_v9.zip stuff?
3. There's not deckbuilder per se for 2013 correct? We just use the in-game builder or ?
