There are a few motorcycles with spokes that take tubeless tires, the Rebel 450 being one. On those bikes, the spokes do not protrude inside the rim, which allows them to be tubeless.
Changing a tube type tire isn't a whole lot differnt than a tubeless one with the exception that you have to be careful not to pinch the tube when mounting the tire. Doing so usually results in a hole in the tube. There are lots of how-to videos about changing motorcycle tires on YouTube. It's basically the same as changing a tube type bicycle tire. Having several tire levers/spoons the appropriate size helps. New tires go on much easier than the old ones come off!
I have found it's easier for me to cut old, stiff, tires off the rim once the bead is broken and the tube removed than it is to fight getting the bead over the rim. I carefully saw through the tire with a hacksaw until I get close to the steel bead, then use wire cutters to finish the job. Be careful not to damage the rim with the saw.
The old tube may still be good, providing it hasn't been damaged beyond repair during removal. Exposure to the elements and especially sunlight is what damages rubber. If the tube is soft, pliable, and looks as new, it is probably fine to use it. OEM tubes are usually much better quality than replacement tubes.
