how on earth do you go about creating 360VR movies? - I have a Canon 350 plus Sigma 10-20mm lens....

The PhotoStitch software that came with the camera does a good job of it if you have a decent set of panoramic shots (covery the full 360-degree view) to work with.

sorry but that isn't much help.. can anyone using this equipment or equivalent give me any specific information on focal length used, tripod set-up, software, workflow required?

1. when taking the pictures make sure the tripod is level and that the camera is also level.
2. if you have a light meter use it rather than the camera to get a light reading off the light source, set the camera to manual and shoot at one setting rather than letting the camera change the lighting depending on direction of the camera.
3. shoot pictures so that there is plenty of overlap (i.e. the left third of an image should be the right third of the image next to it) this will help the computer mesh the image due to the different perpectives of being on the right or left of the picture.
4. the focal length you are using will determine the number of images you need (i.e. the wider you shoot the fewer images you will need.) (also i.e. you can use any focal length you want, but high focal lengths may be overwhelming to put together.)
5. play with the photostich software. Generally the software provided is fairly user friendly for stictching images together and trying to equalize the coloring of the different images.

Hope that helps.

another few things to add to the comprehensive list by Loki1117

Don't go too wide with the focal length as the distortions will make it trickier to stitch.
Don't keep the WB on auto, pick one of the presets or shoot RAW and correct later.
Nice low ISO.
Use the lens' hyperfocal length to get most of the scene in focus.
Use a medium aperture f/11-f/16 to get a good DOF.
Try to keep complex objects in the centre of a frame, stitching 2 halves of a tree together is a PITA.
Use one of those hot shoe bubble levels
