Ok,

Will a 32-bit application install and work in Vista 64-bit OS?

No doubt there are a few exceptions, but nearly all 32-bit programs
will work in 64-bit Vista.
 
it depends on the application. x86_64 platforms should run most x86
applications, but some x86 applications don't bode well with the new
architecture. I suggest you try it and see. If it works, you'll have better
performance.

also some programs need to install a shell extension (dll) for them to
work, but if the dll is 32 bit it cannot be loaded onto the 64 bit windows
explorer...

thus they fail

in sheer contrast with ubuntu that EVERYTHING (and I mean everything even
the flash player from adobe is 64 bit while they ignore the windows users)

is 64 bit and fast as a speed demon utilizing the full power of 64 bit...

64-bits doesn't make things faster, per se. In fact, it can make things
slower because of the wider word size. An example are applications that do
not fully exploit the text cache because they are poorly written. When
compiled as 64-bit, the code will take more space and will make even poorer
use of the cache.
while windows needs to use an "emulation" for the 32 bit apps.

Really? Didn't know that Windows had to emulate anything. I thought there's
a Win32 and a Win64 API and that the 64-bit versions of Windows do support
both APIs.
they still are confided to the limitations of a 32 bit application
memory-wise ....

and this includes programs that would be great with 64 bit like Photoshop.

I'm not entirely sure how PhotoShop benefits from a 64-bit address space,
unless you are editing really, really huge photos (>2GB). Is this ever the
case? If 64-bit PhotoShop is faster is not because of the 64-bits, but
because when running the processor in native 64-bit more CPU registers are
available, which is leveraged by compilers.
