inspiron duo help

i recently purchased a refurb inspiron duo and am trying to use it the best way it can be. the Stage software was not installed but i finally was able to get that installed except for Photo Stage. I am desperately trying to figure out how and where i am supposed to get that software, since it was one of the main reasons for purchase. As, well I am also trying to figure out how to edit and organize my music in Music Stage. Lastly, i would love to know where i can get the best apps to use on the system besides intelappup.com. I welcome all and any assistance! thanks!
