I actually saved quite a bit of money by going with a 7mm static rope rather than a 9 or 11mm dynamic rope. No doubt, if you're climbing and are going to fall down to the last piece of protection, this would be an absolute no-no. Static rope has no stretch and if you fell on it, it would put tremendous stress on both your equipment and your body, likely leading to severe injury. All rock climbing should be done on a dynamic rope, which can stretch up to 1/3 its length and absorb a tremendous amount of force. On the other hand, for rappeling, a static rope is fine because your speed is controlled and there are no sudden jerks. You can also buy it from most climbing shops by the foot off a 600' roll, whereas most dynamic ropes come in two standard lengths, 165' and 180' (although you can order longer lengths up to 600'). My proper 11mm dynamic rope is 165' and cost about $125 in the late 1990s (and should probably be retired). My 7mm static rope is 150' and cost under $75 ($65 if I recall correctly, but I bought it when I got my current job back in 2001 and I'm too old to remember that far back with any accuracy).
Another consideration is to have a hammer or hatchet with a teather on it. Completely innocuous, makes a great self-defense weapon, can get you through a drywall wall in a hurry, and if you need to remove a window, it'll make quick work of the task. Remember, her best idea for escape may not necessarily be going all the way to the ground, but just going down a few floors, so she'll need to have a way to get through a window when she gets there and tempered glass does not break nearly as easy in real life as it does in the movies.
As for the smoke hood, you can find them as cheap as $65 on up to about $125. I even keep one in my suitcase for hotels when I travel. It's a lot safer to use a smokey stairwell than trying to rappel.
