This should work almost "out of the box" (famous last words...)

I'm surprised the manual didn't help you.  Do you have the
full Texinfo/DVI/PDF/PS manual?  It should be out there somewhere.
The next release of DDD which is coming in the next couple of
days, will include the source to it.  Currently, only the 
ps is distributed (if I remember correctly).

DDD works by sending commands to gdb, and parsing the results.
That means if your cross-debugger is running locally and
communicating with your embedded device via a stup, then 
DDD doesn't care at all that your gdb is a native or a cross
debugger; the commands are still the same.  All you need to do
is to run 

    ddd --help,

which tells you (among other things):

    --debugger CMD     Invoke inferior debugger as CMD.

So, to answer your questions:

1. No; ddd doesn't need to know about the target.
2. It's in the manual.
3. The manual should be in the source distribution
   (if it isn't, please let me know, and I'll fix it).
