For scanning, I use a cheap Epson V500. At less than $150, it is about as good as I could do with a flatbed, and until I can save up enough pennies for a Nikon Coolscan, it does the job just fine.
Film, well, you can read up on that till the cows come home. Best thing is to get a few rolls of a few different types, and shoot them. Films can all be developed in different ways, so I find that trying to find sample images of different films online is a wasted effort. We could both shoot the same type of film, but depending on how it was dev'd, it could look completely different.
