Like myself a few years ago, search the forum for information as you are the not the first to ask how to start. I think this week alone I've seen 2-3 simliar "I'm new, how do I start" questions posted!
You will need primarily a dedicated panoramic head. Nodal Ninja are a popular brand to use. Next is perhaps a fisheye lens. Dependant upon your budget dictates the lens you buy. Samyang or Sigma 8mm fisheye lenses are popular again.
Once you have the nodal point set on your panoramic head (search google for how to set this or this is a good place for info: http://www.johnhpanos.com/tuts.htm)
Next is to learn, practise and keep practising the practical aspects of photographing a subject and the tricks to adopt when shooting. Looking for best position to shoot, minimising shadows, understanding how the equipment is set up and how to use it etc.
After that you can then learn and practise how to stitch the images in this software or other stitching software to get the best 360 equi image created.
Lastly after that you can learn and practise some more on taking that stitched image and converting it to a 360 deg flash file that can uploaded/embedded into a website.
I did not have any training to me, only the interest and patience to research the processes involved, obtain the correct equipment to do the task and then become familiar with the software that makes our art possible.
As my father says to me, "It won't get handed to you on a silver plate. If you want it, you need to make it happen yourself"
Ask away here with any questions and I'm sure we will help out if we can.
