No. Unless you are making major changes to your system's hardware, for example, replacing the hard drive, proccessor and motherboard at the same time, reinstalling the OS is not necessary. Sometimes even making major changes to the hardware will work ok without any reinstalling. The exception being if you replace the hard drive that contains the OS.
If your computer does not meet the minimum RAM requirement for Vista, an upgrade will increase speed.
You can upgrade your computers perfomance by purchasing a memory ram upgrade or you can look into getting a more recent operating system like Windows 7 or Windows Vista.

That depends entirely on what type of upgrade you are performing and your proficiency in doing so. Upgrading the amount of RAM in a system can be done in less than two minutes by a skilled technician. Upgrading the video card will probably take five to ten minutes. A motherboard upgrade will probably necessitate reinstalling the operating system, and require over an hour to perform.

This is a common occurrence, particularly if you did not upgrade the computer beforehand. Windows XP requires more RAM and a faster processor than Windows 98.

Whatever memory your motherboard can support but a 64bit version of Windows is needed to manage more than 4GB of RAM. Generally people use 32bit version ram for all the Windows Operating Systems. So for that it is enough to have 1GB ram. I think 1 GB ram is more than enough for it. In case If you prefer to choose a 32 Bit version of Windows 7 Then you have to upgrade your hardware to 1GB or more than that.
You might as well buy a new PC if you want to update and you have that setup.
You can only install 64 bit Windows Vista on a machine with 4GB ram. If you have enough ram then you need to do a clean install. To do this boot up your machine with the 64 bit Vista CD. Then follow the on screen instructions.
Windows 7 requires more RAM and processing power than Windows 98 computers because of its enhanced UI and the amount of background services it runs to make your computer work and function properly. It might possibly run the lightest version of Windows 7, called Windows 7 Starter.
