2002 Cadillac Deville Engine Trouble

A few months ago my 2002 cadillac deville started burning oil alot, and it keeps failing emission. About a month the radiator hose broke and I had it fixed, now the engine is runnig hot, the car is leaking antifreeze and there is no heat inside, the car runs but we have to keep putting water and antifreeze in it before we get to our destination. When it does run hot I hear like a boiling sound and sometimes see a blueish smoke coming from the tailpipe. What do you think the problem could be?
