Hi ffj - I'm hoping here that you mean scanning radios and not other kinds of scanners, such as document scanners. Those are a completely different animal.
Note that anything in blue is a link of one kind or another...
To start, I would read the Scanning 101 article linked below - this will get you introduced into the scanning world and exposed to some of the terms and concepts...
Scanning 101 - The RadioReference Wiki
Bombay NY is in Franklin County - we have an online database for that area, and there's a website with its own listing of information. Even if you don't understand this yet, bookmark them for future reference...
Franklin County, New York (NY) Scanner Frequencies and Radio Frequency Reference
NF2G - New York
Understanding what is in your area is
critical to buying the right scanner for the right application. Unless you are interested in hearing the power company, it looks like an analog trunktracker or even a simple conventional scanner will do very well. However, I would investigate further in our NY forum, as you may find folks local to you to give you better information...

Most all scanners these days can interface with a PC via a USB connection (with a few exceptions, this has to be bought seperately) and the proper software. When you choose the scanner you wish to use, you will also know which software is compatible with it (there are some links in the Scanning 101 article for this). If your mobile computer is running Windows XP, Vista or Win7 and has a USB connection free, chances are it will work just fine for programming - and, depending on the model, controlling - a scanner.
