Windows ICE is fast and does a fairly good job. Just dump the photos into it and rather quickly it will make the pano, disregarding photos that don't belong. For online viewing, you can upload the panos to Photosynth. I've recently done some interior panos of an old 19th century coastal defense fort (Ft. Barrancas) in Pensacola. Magic Lantern to take the photos (auto HDR), Lightroom to stack and blend the images. I find that the blended images usually need some enhancement after blending and it's easy to stay in Lightoom and do that. I use ICE to make the pano and upload to Photsynth.

Hugin is my second choice, it does an excellent job but is far slower. It's a good front end for much of the software useful for panos.
I'm strictly a hobbyist and most of my work is done on a Vista laptop, those of you with more powerful computers will likely find other methods that work well for you.
Like most aspects of photography, this is one where you can take many paths to get to various flavors of your destination.
