Although the Matterhorn doesn't offer Fast Passes, it does have a single rider line which can save a lot of waiting time if you are willing to break up your party when riding. Single rider lines are also available for Splash Mountain and Indiana Jones Adventure, and are especially useful next door in Disney California Adventure on the extremely popular Radiator Springs Racers.
With the exception of Star Tours, I'd consider all of the above attractions must-sees even if visitors have experienced them at Walt Disney World, and I'd also note that while Disneyland and the Magic Kingdom are very similar, there are enough unique attractions at Disneyland that Magic Kingdom visitors should still plan at least a full day for Disneyland park itself (I'd recommend two days, or at least a day and a half, for first-timers who have not visited Magic Kingdom). One other tip: With the exception of Peter Pan's Flight, the Fantasyland dark rides usually experience significant wait time drops during the parade, so if you're not watching the parade this is the time to ride them.
As for eating, read the Blue Bayou's menu first before making a reservation to avoid sticker shock.
And if you need mobility help, especially ECV's, get them EARLY! They often sell out early, around noonish (OK, I'm a local. That's early for me), and you'll need to get put on a waiting list. Kinda like Fastpass, but much less fun. You'll give them your cell phone number, but Disneyland phone service is not the best, especially during heavier times.
