Unless there is anything else, it sounds like Haynuus will go bakc left to the bodies, and Farel will go right to the stairs, with him assuming you can open he door again.
Just to allow you to play ok, at worst a take 20 search will reveal the switch to Falkor or Helm. Aurek and Haynuus can probably do the same because they saw the switch (so if Haynuus isn't in a rush, he can let himself back in - and infact needs to if the party shut the door), and Ameena's perception is good enough that she will be able to spot the switch with a take 20 (providing someone tells her the right area to look) even though she hasn't seen it herself.
The magic users won't actually need to properly 'rest' to get their spells back, now the adreneline has worn off, the mages should ave their spells pretty quickly and can start castng spells again as they relax. Note that aurek's 'lay on hands' won't come back unless the party actually settle in for another long sleep. If you guys want to do that.... well, you can if you really want.... Othewise, RP wise Helm and some of you might feel you want a proper rest, but mechanically you are good to go in five - ten minutes
Oh, unless you really want to roll, Westian and Aurek just pool together you healing dice from your VI potions that you cast, assume the average of 7 hit points per 2d6. Use that to figure out how long - assume your spells refresh every 15 minutes.
Money - note that Falkor could keep casting FUL spells at this time and stacking them together then recharging. The plus side would mean not using torches for light (keeping them for when needed), while the bad side is that they are focused on Falkor, and he currently has no way to undo their light incase the party actually need to have darkness
