I wouldn't use any of it. The first thing that gets tossed when I adopt new crabs are the pellets.
Check out the safe food list linked above and you will find that you can feed the crabs for next to nothing by picking bits off when prepping meals. Just take some scraps before seasoning, keep eggshells, etc.
For water you want marine grade salt mix such as Instant Ocean. There are other brands but this is the most commonly used, probably because it is easy to find.
SeaChem Prime and Kordon Amquel Plus are good dechlorinators. The Prime only takes 2 drops or so a gallon, and one small bottle lasts a long time. I have not had to replace mine in 2 years and I have large pools in my tanks.
Be sure to read the guides linked above, if you can return the items and exchange them that would be good. Unfortunately they are just not really good for the crabs.
