Is the fitting and hose that comes from the rear top of my engine and runs into the passenger side firewall to the heater core?

Sounds like it may be?
Is it about a .75" - 1.0" Hose?
Because that is the normal size of heater core hose.

I have a problem with the heater hose it broke off from the croe

It's common. there is a special tool to remove the plastic peice that is stuck on your hear core. Most all parts store have them. The size you will need is 3/4". they usaly come as a set with muliple sizes.
Then after you get it off you can replace the hose. Make sure the other one is in good shape. Most of the time they will both fail within a couple of months of each other.

2000 gmc sierra 5.3l heater does not get hot

After replacing the thermostat I pulled the heater hoses off and blew air through the heater core at firewall. Can only blow in left side as directional valves will prevent opposite. Chunks of stuff came out with coolant. I then put a piece of hose on the left side and shot water through until it came out clear.
Put it all back together and heat works fine.
