Sorry to hear that you are having problems. I am planning to post some more video tutorials in the near future, but I need to make a few more changes to the plugin first.
I'm afraid I can't debug your layout issue without seeing the site. If you can get you local site onto a live dev server and send me a link, I'd be happy to help you get the slideshow to layout properly.
But you can certainly wrap an extra dive around the slideshow if you need or want to, it won't affect the slideshow any.
As for the multiple slideshows, not let them frustrate you :) The slides are just like posts, and the slideshows are just categories for the slide posts.

Then you should be able to add the slides to those slideshows just as you would posts to a category.
Then you just need to specify a slideshow when you add the slideshow to your page. Like of you added a slideshow to the content of your about page, it might look like this:
