yes.

basically correct.
Pd itself does not have any problems any more with 64bit.
there might still be a few externals that are incompatible with 64bit 
mode (that have to be ported, because they use low-level tricks), and 
more externals  that still miss the "-fPIC" flag (this is rather trivial 
to solve when compiling)

both the type of numbers in messages (t_float) and signals (t_sample) 
are still single precision floating point.
In Pd-0.41 the types t_float and t_sample are used almost everywhere 
(where applicable), i hope that i will have patches for pd-0.42 that 
will allow you to compile Pd with double-precision.

Pd has been in debian/amd64 for some years now.

i don't know whether günther has backported all the 0.41 fixes for 64bit.
personally i always have the debian-packages installed and never use them.
