The location of your app can be /usr/bin or usr/home/username/yourapp 
Of course /usr/bin will require password to be able to be installed. 
Sudo or su will get you through that (ask the user for the password in 
advance.)

Their menu specs are here:
http://www.freedesktop.org/wiki/Standards_2fmenu_2dspec

For more specs linux related:
http://www.freedesktop.org/wiki/Standards

Here are some locations found for shortcuts on linux:

/usr/share/applications
/usr/share/applications/kde
/usr/share/gnome/apps  <- some sub dirs with shortcuts
/usr/lib/menu <- text config files for shortcuts
/usr/share/menu  <- text config files for shortcuts
/etc/menu

Setting up a menu entry is still iffy if you ask me, but if you stick 
with the freedesktop specs, you're more likely to have a working menu 
entry since most distro's are adopting it.  Otherwise, as you already 
know, there's a mess when it comes to the shortcuts.

Gnome used it's own location, KDE another, and all the other WM's 
probably have their own location also.  :-(

For file types, I don't remember at the moment.

I don't believe there is a way to actually assign an icon to an 
executable in any of the window managers.  At least I didn't see of any 
way under KDE or Gnome, just the shortcuts and menu entries have the icons.

And I can't remember how to assign a specific icon to associated files 
at the moment.  Been a while since I mucked around the innards of a 
linux system.

Personally, I think the menu shortcuts are still the only major issue 
you will run into.  And imo I'd setup shortcuts in the KDE, Gnome and 
freedesktop locations to insure that you get most, if not all of the users.

The other issue might be, what the equivalents of sudo and su are on 
other flavors of linux.  I know sudo and su are on debian, but not sure 
about the others.
