Just knowing the plant is a Yucca helps me a lot, and you are right, it is a Yucca. From some quick research, it looks like the spots are a fungus, which I suspected, anyway. Thank you!

For the Roses, I haven't sprayed anything, but I was told a landscaping company came in before I took possession of the house and did some spraying and/or fertilizing. Could that be the cause? Will leaf burn negatively affect the plant (other than the obvious burns on the leaves)? Is there anything I can do other than trim the burned leaves and take care of the rest of the plant?

As for the tree, I've attached the largest picture I have, which still isn't that great. There really isn't much to see, though. It just looks dead - no leaves except on the very top of the tree, and the bottom of the trunk is bent, as if it grew from the ground crooked. The branches are still pliable and other than the fact that they're covered in lichen, look healthy to the untrained eye. The leaves on the very top of the tree don't look as if they matured, but they're green and crisp.

One thing to note - we think there is some sort of burrowing animal in the yard. We are finding holes and tidy piles of dirt where no holes or dirt should be. We have no idea what it is, yet, as we haven't seen anything. My first thought is gopher, but I would think they'd be easy to see. At any rate, would a borrowing animal kill a tree in this fashion?

Thanks so much for the help!
