Moving PowerGallery & Settings

I'm just starting the development of a new site using Powerstore3 and Powergallery. The current site is built using eCart and other WA extensions. While developing, I created a new directory called "new_site" and uploaded that to the server. Everything is inside this directory and is working so far. But I'm very concerned that when I'm ready to eliminate the old site and copy the new PowerStore and PowerGallery over to the root - things are not going to work. For example I noticed the code that I pasted into the description area for the powerstore from the powergallery has an absolute path that will be incorrect. Am I right? I could easily move the PowerGallery over to the root, but the rest of the site contain some of the same named files and I can't do that. I want to do this right from the beginning.

Then I have a couple of styling questions regarding the powergallery. I see on the index.php the wrapper is set to auto for left and right, which centers the strip on the page. I want it to be left justified to line up better with the photo above and the text below (Products_Detail.php?ProductID=1). I've tried a million things to the index.php and the stylesheets, but nothing seems to take.

And, from what I can gather, I cannot turn off the floating details/image name from appearing over the thumbs - is that true?
