AUR and Kernel Questions
I'm considering using a Kernel geared for AMD cpus, and rather than compile it myself, I'd like to use the one from AUR.
I'm planning to familiarize myself with the AUR risks and benefits.
What planning should I consider when using AUR, and specifically using a custom AMD kernel?
How might using a custom kernel affect updating, using pacman -Syu?
My current setup is that I have a vanilla kernel, booting with Grub, using Luks, and Btrfs with Grub on a fat partition and the kernel on a single btrfs partition.

You'll still have to compile it on your machine if you use PKGBUILD from the AUR. You just will not have to handle the configuration yourself.

Read and follow the AUR wiki page. That's it.
For a custom kernel, you'll also have to either use dkms versions or build your own versions of any out-of-tree kernel modules that you may use.
How might using a custom kernel affect updating, using pacman -Syu?
It wont. But, hopefully obviously, pacman will not update your custom kernel: you'll need to rebuild it whenever you want to upgrade it.
Why do you want to use a custom kernel? If it is just for AMD-specific optimizations, I doubt you'll see any benefit. And if you are not doing any of your own configuration, then you may just want to use one of the unofficial repos: Graysky maintains a repo of ck-kernels with cpu-family-specific builds.
