Community @ The Turning Gate

I want a lightroom template for rebuilding my personal website.
The MAIN thing I want is an interface that works the way I want. I've got some specific wants/needs:
A. Three+ levels of view:
0. Index of galleries, perhaps in a heirarchy, with plenty of "hooks" for custom links. (I could do this myself, though)
1. Gallery Index grid/table of thumbnails, with configurable thumbnail size.
2. Normal Full size view, with configurable size in gallery.
3. True Full Resolution size view. It should allow zoom in/out, panning through a huge image, and gallery or image level definition of a watermark for the high resolution image. I presume this might be a java or flash applet or viewer of some sort. Autopan option for large panoramas would be a very nice plus.
Ideally, navigation should allow you to go to the next or previous image or gallery, depending on the level of view, and up to a higher level in the various levels of view.

2. Ability to use (at a minimum) Title, description, and ideally selected metadata in the template, in html form, so each image appears on a page with its own specific text/keywords, so that search engines can find my images optimally.

3. Shopping cart for the site and print ordering per image at a commercial vendor, or preferably more than one commercial vendor so we aren't locked into a single solution. In it's most ideal form a metadata could be loaded with info for the widget/link(or whatever) so we can stay on our personal website, but order via a POD site with easy return to our website

4. Keyword filters so users can search for image keywords, title, description, and metadata values.

5. Open architecture for template customization. (Optional, but would be very nice!)

6. I'd like to export images in three versions: thumb, medium with optional watermark, full-res-with-watermark.

I know that's asking a lot. Most of the templates are definitely lacking in the bolded items. This web template technology is pretty old, and it's time that somebody offered all this in a single template. They're pretty basic for a photographer's needs.

As far as customization goes, I'm very old school. I know SQL,  elementary HTML, and some really old languages like powerbuilder, foxpro, and Clipper. I've written code generators in all three, but I it would take me a lot of time to do that for Lightroom, since the database does not appear easy to reverse engineer. And I still wouldn't have a workable cart and POD connection... I guess if I have to learn JS, I could... (Other tech to learn?)

For an example to comprehend my concerns, I have a lot of very high aspect ratio panoramas. Like this one:
Painted Desert Panorama 1/3x1/3 of full resolution. Click in your browser to see it bigger.
