Cedric, Hi, For starters: http://eewiki.net/display/linuxonarm/BeagleBone+Black this is Roberts "build your own" guide.
http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-RootFileSystem%28smallflash%29 This base image is around 75M in size for me without anything else installed. WIth openssh-server, and ntpdate, I think around 91M size total. As for the rest of your questions: I do not know personally. I do not use QT, or an LCD. As I run headless, and have no interest in either for my own purposes. Instead I use my own BBB as kind of a network appliance by using Nodejs.
