2) When playing for fun, the two easiest modifications are to ease off on scratch rules and calling of shots ("trash counts"). When just playing for fun, it's pretty common to reduce the rules to basically "you have to hit one of your balls first and if one of yours then goes in, you get to go again" and as far as scratches go, only pick up the ball and place it if the cue ball goes into a pocket or off the table. For other scratches, just play it from where it ends up. Tons of other variations for casual bar/home play, though.
