I was going to suggest the DM adopt a sandbox or open ended style, but since you've said she's new, that probably is easier said than done.
Part of me wants to suggest dumping the lame players.
Part of me wants to suggest dumping the adventure path.
Part of me wants to suggest hiring henchman and continuing when the 2 lame players sit back and watch.
So, I reread your first post and focused on this: "she suddenly tossed the adventure path away and said "I don't think I want to do this anymore".
Sounds really like a break is needed, but I suspect from experience that would result eventually in no game at all.
So, the DM should consider cutting down her prep time. Use this as her opportunity to learn some off the cuff gaming skills. I'm NOT suggesting dumping the adventure, rather, don't worry if she reads the wrong text or can't find the description of the room. Make it up! Can't find the stats for the undead wizard? Just find something close and go with the flow. How are the players going to know the difference? They don't want to go into the evil shrine? Fine, skip it and put the info they need into the next encounter.
The point I guess I'm trying to make is the DM should put their time and energy into other avenues, which may not be related to her previous experience with the Age of Worms.
