I think you posted this also the 1ds forum, but
Make sure you check out the
www.outbackphoto.com stitching forum. lots of info there.
A few points,
Don't even worry about the canon software. There are many others on the market that will work better. Best I have seen is the realvis, but it's just too high currently.
My solution for physical gear, changes from time to time, but currently:
I use either a Gitzo explorer, with a Bogen 755 B leveling base, then a RRS BH-55 with a RRS pamorama clamp.
Or the Bogen 3443 carbon 1 with the Bogen Leveling base for the carbon 1 series. Same ballhead.
It's very important to make sure your base is level, and don't confuse this with the ballhead being level. The ballhead must rotate around the base, thus if the base is not level, your pan's won't be either.
Leveling a tripod is a hard to do, harder than most think especially in the outdoors. Having a leveling base just makes it a simple thing to do.
Consider shift lenses or shift adapters, ton of stuff on the outback site and on the 1ds site on Rob's site. Zoerk's PSA is a good place to start.
The nodal point is not that big a deal unless you are panning with objects up close and distant. Net, if you are shooting a pan of the Grand Canyon, the nodal point is not as important, at least in my thinking, as if you are shooting some of the stuff I shoot, where I have subject matter from 5 feet to infinity to worry about.
