Gallery integration is done through any HTML Editor instance. The toolbar now has an "add gallery" icon that will allow you to add a galery to any product long description, or any content area.
In terms of images, if you want to use the same image for both, only specify the image on the first tab. It will automatically use it for both if no second image is specified.
You noticed my catelog typo :( I'll get it corrected before the final build.
The pp_confirm page should have asked you to enter a password. If that field didn't show up, then that sounds like it could be a bug.
We have made our bed with the supplied themes. Luckily they are mostly configurable from the admin to adjust and lighten the colors. In each future version we will try to create a few new themes and will keep in mind that there is a need for lighter ones.
We will make sure that you can edit the crazy background in the next build.
To delete a created theme, just delete the folder in /webassist/themes/ with the theme you want deleted. Currently this has to be done manually.
