I am trying to set up a loopback0 port on my 3550-24. I want to use it as my management port. It lets me configure the loop back.
ip address 10.244.244.24 255.255.255.255
ip broadcast-address 10.244.244.255
But I can never ping it from my work station. I can't figure out what I am doing wrong. Can anyone help me please?

There are at least 2 issues here. First and most important you need to enter the command ip routing to enable ip routing. Currently your switch is operating as a layer 2 only switch. You need to enable layer 3 processing to forward packets between VLANs and subnets. Without ip routing enabled it certainly will not do what you want it to do.
Second issue is the attempt to configure the static route. Here is what you entered:
ip route 0.0.0.0 10.244.244.24 255.255.255.255
it appears to contain the destination address, the next hop address, and the mask. But the mask needs to go immediately after the destination address. And the mask is inverted. so it should be:
ip route 0.0.0.0 0.0.0.0 10.244.244.24
Also as a layer 3 switch I am not convinced that the switch uses the loopback interface in the same way that IOS routers do. So even after you address these two problems there may still be some issues
