There is 3 way to go, Ipix, QuickTime VR and Java Applet. The later is the most accessible because it requires no plug in or special viewer on the client's end. On the other hand QuickTime VR offers more features. I care for a couple real estate sites using panoramic technologies. The best thing is to offer all the alternatives to visitors, from a simple picture slide show to Quicktime, with Java Applets in the middle.
One panorams tool I love is "Ulead cool 360" Allows your users to move round as if they where turning their head. Would be excelent for virtual tours. I have to admit though, I have never actualy used in as part of a website.
Having researched this in the last few months, there are some quite good free tools on the market (if you see what I mean) - I found the panoguide.com site very helpful and ended up using MGI Photovista which was included for free on the Dreamweaver 4 CD (which I hadn't realised). You need a java applet to display the photo - again there are some reviews of them on the panoguide site (I use the Sven Meier one as it isn't very heavy).
I am a bit unsure what you are asking however. Photosuite appears to include the stitching software, so you should have that already. The steps that I would take are to use Fireworks to do any retouching and resizing work on the pictures, Photosuite for your stitching, possibly retouch with Fireworks, and then your HTML editor of choice to integrate the stitched photo and applet into your site.
I went to DMOZ like suggested and found a great site called panvue which made use of their free trial with in an hour of fiddling and messing about I had my Panorama view of 180 degrees.
Although it was first ever attempt, I am pleased. The free trial places their small logo in the images but for a small job it was o.k
