Welcome to the free software community, Brian!
I have found that most suspend/resume issues are magically solved when installing a more recent kernel, such as linux-libre 4.1. I would recommend that you follow the instructions here. Scroll down to the heading "Using jxself's repository". When you come to the heading "Installation of the new Linux-libre Kernel" you might want to open the "Synaptic package manager" to find the linux kernels.
