User Manual Mr. Coffee DW13 Coffee Maker, 12Cup Switch

Unfortunately this model does not have any auto shut offs.

We do not have information regarding how fine you will want to grind your beans. As this may be determined by taste.

Yes it will keep it hot, but leaving it on a long time will make the coffee stronger, I usually put it in a thermal pitcher, and use it from there.

Yes they have replacements for the glass coffee holder.

It is very fast. In fact, the water flows through so fast that I double up the paper filters to slow it down so it isn't weak. I have a pot of coffee in about 7-10 minutes? I have not timed it.
