two of your questions i can answer right away,

flashplayer should be easy, open a terminal and type
Code:
sudo apt-get install flashplugin-nonfree
and
emulator, uhm,
Code:
sudo apt-get install wine
then you run winecfg, you can do this by typing "winecfg" in the terminal or looking it up in the menu (under system I think)

if you wish you can use synaptic to insall programs instead of the terminal, synaptic will show a loooong list of available and installed programs and has a search function.
just avoid updating, i have from experience found that to break things.
