Hi, welcome aboard!
as for scanning, see if Wiggy or Arseen can give you the "idiots guide" version, there the scanning experts, but as long as you scan at 300dpi minimum, absolutely flat and square with moire removal/descreen on you should be good to go...
whereabouts in the UK are you? (presume uk from UN and "pal cases", )
also, could you post a list of the games your thinking of scanning, some covers may already be available in the forums, might save you a bit of work...
