1. Check each image, there are options for how the view is displayed, including "camera default" or "which direction you walked here from". If the "camera default" is backward from what you expect, rotate the camera (180 degrees by the sound of it) in the scene to re-render, or there may be some option to set a fixed direction among the camera default and direction you walked here from settings. I usually go with "the direction you walked here from" since that makes sense from the perspective of walking around through the scene :) And then it doesn't matter what camera orientation was used in the scene (except for the first image that starts the virtual tour)
2. Labeling hotspots for automatic hotspot generation can be done by labeling the image filenames, so an image for the living room called "Living Room" will cause its hotspot to be called "Living Room" by default. I generally rename the images prior to uploading them (click the image name in the "upload to collaboration" dialog in the VFB), or you can rename the images once they are uploaded then re-run autohotspots and all connections to the living room image will be renamed "Living Room" (easier than editing each hotspot manually after doing the autohotspot generation).
Let me know if that answers the questions!
