1. Right click -> Library Tools -> Clean File Properties -> Check Move articles to end
2. I would create a new field (Tools -> Options -> Library & Folders -> Manage Library Fields... -> Add New Field) and use an expression to combine whatever fields you are looking to combine (Album, Sample Rate, File Type, Etc). You can then either rename your Album with this new field, or just customize your views to use this new field instead of Album.
Before you go through the process of renaming all your albums though, you may want to search and read some of the threads regarding albums with the same name. It has been discussed many times, and many people prefer to keep the actual Album name but do other things to arrange their views better. For example, if you have different file types (ie FLAC vs MP3), you could stack the tracks with whichever version you want on top (

Then I add Description as the bottom child level in my views. So in the manner you use, it would be Artist -> Album -> Description. You could set up Auto Import so that certain folders are auto-tagged with whatever Description you want.
