I can't help with the skipping issue other than to suggest cleaning the laser, but I had the same drawer issue and repaired it today. If you open the case and watch how the drawer works, you'll see it has a small spring-action metal catch/latch with a tiny white wheel on it at the rear of the slide that the drawer moves on. The latch engages with the slide mechanism when it is closed. I put some dry teflon lubricant on the latch and slide then slightly bent the latch away from the drawer to relieve some of the pressure. It works fine now.
