Depends on your CPU, basically 32 bit is what most people have, 64 bit are newer processors, like Athlon 64. I am not sure, but 32 bit Vista 'should' work with a 64 bit CPU, but you wont get the advantages that a 64 bit version offers.

It is true that Vista x86 will run fine on a 64-bit processor. It is not true that it will not benefit from the more advanced cpu. The 64-bit processors have more "headroom" and 32-bit programs can benefit from this even if the extended instruction set is not used.

Yes it is.

That's silly, 32bit code isn't going to run any faster or better on a 64bit processor than it would on a 32bit processor. Any "headroom" WhateverTF that is, doesn't make any difference at all. The 32bit code doesn't know that it exists, and it's not accessed or used in any way at all.

Yes it does. The 64-bit processors provide greater headroom (more and wider registers etc).

Wrt the width of registers, 32bit code, by definition, does not know that registers can be wider than 32bits, and so it will *never* access more than 32bits of a register. If the code knew how to use general purpose registers that were wider than 32bits, then it wouldn't be 32bit code.
As far as there being more registers, that doesn't make any difference either, if the software does not know that these additional registers exist they will not be used... period.
I can beleive you're really trying to sell this "headroom" mumbo jumbo.
