knowing nothing about scanners, I MAY be able to answer your last questions - if a scanner does indeed work like a keyboard, then you can capture the text changed event, HOWEVER, you may find that this event is fired as each digit is entered. Therefore you should check for an expected length, or build a system with a time-boxed buffer so that you can make sure you have captured all of the barcode.
Then you can do the database lookup and display the results you need. CK PS. This is assuming you are using a WinForms application, if it is webforms then you need to do some AJAXY stuff.
