Writing, calling, whatevering to Disney is usually fruitless. Most of the CMs on the phone aren't at WDW. Even if you are in your resort room and call "the front desk" it goes to a call center. They may be able to tell you the correct answer for the rack room rate for a given night, but other things are hit or miss. If you call 3 times, odds are you will get 3 different answers.
Similar toasters, condiments may be different, seating is bigger. And I think the values may have more toasters/microwaves just since they are bigger food courts. Look at some of the pictures in this gallery ->

The condiments/fountain drinks are usually similar, but will vary by resort. For instance I usually find that the values only have 2-3 types of tea bags out, and even then you may need to ask at the register for the tea. But the deluxes may have 8-10 styles, and often left them out all day. And even with things like the Rapid Fill systems, for a while at least some of the managers at the deluxes disabled the system as they were getting to many complaints, but I've never heard of that happening at the values.
