Other than allowing you to reference much more ram then no. 64-bit will improve computational processing not your every day tasks. If you are trying to use finite element analysis software such as comsol for research than I would recommend the 64-bit architecture.
The main advantage of a 64 bit operating system is that it can make use of all the features and performance of a modern 64 bit microprocessor. If you run a 32 bit operating system on a modern 64 bit microprocessor the operating system will not be able to make use of any 64 bit features of the microprocessor and the performance will not be what the microprocessor is capable of.However a 64 bit operating system WILL NOT run at all on a 32 bit microprocessor (or one with a smaller word size) as the microprocessor does not implement the 64 bit features needed for the operating system to work.Note: in the not too distant future microprocessor manufacturers will release 128 bit microprocessors, which will require 128 bit operating systems to use all the features and performance of these microprocessors.
I would check the various manufactures web sites about their 64 bit offerings. 64 bit machines offer better performance (and higher prices) than their 32 bit counterparts.

Windows XP is almost NEVER in "64 bit". You have to specifically purchase XP 64 bit, as opposed to regular XP which is 32 bit. 64 bit processors will run 32 bit XP without problems, but you'll get a little more performance and some extra features (GUID partitions) on 64 bit windows. Once again - it's "always" in 32 bit, unless you go buy 64 bit.
64 bit laptops, usually have more memory and a better processor. They are good for power users more than the average user. If you do a lot of photo edit for example, a 64 bit will greatly improve it

The first 64-bit CPU is generally considered to be the AMD Athlon 64, which was released in September 2003. It was notable for being the first consumer desktop processor to support 64-bit computing, allowing for increased memory addressing and improved performance in 64-bit applications. Other early 64-bit processors include the Itanium from Intel, but the Athlon 64 was the first to gain widespread adoption in the consumer market.
There is not much difference between Office 32 and Office 64 bit programs in terms of performance. However, Office 64 has a larger memory and stores more data.
The recommended drill bit size for a 6 screw is 7/64 inch for optimal performance and accuracy.
The first fully 64-bit version of Android was Android 5.0 Lollipop, released in November 2014. This version introduced support for 64-bit processors, enabling developers to create apps that could take advantage of the enhanced performance and memory capabilities offered by 64-bit architecture. While some earlier versions had partial 64-bit support, Lollipop marked the transition to fully supporting 64-bit applications across the platform.
I'm not exactly sure what you're asking here, but I can tell you that any file or program that has "x86" in it is NOT intended for a 64-bit CPU/system. When something IS intended for 64-bit hardware, the file name will instead contain "x64". It MAY be possible to install 64-bit Vista on an x86 (or 32-bit) machine, but not only would you NOT get whatever performance advantages 64-bit has over 32-bit, you would almost certainly have PROBLEMS as a result.
You need a 64-bit computer with a working 64-bit operating system. When you install java it will install the 64-bit, it will recognize you have a 64-bit computer and install it
