If someone says:
Listen to me. Take the phone now, call John, tell him that the money are in the drawer, under my notebook. Tell him to buy bread, and not to go away untill I'll be back at home.
Did you understand all / everything?

What should one say at the end - all or everything?
(And please correct my mistakes! )

And one more question:
One can say "Go to hell!". Can one say "Go to hell from here!" ?

Thanks in advance!
