One of the things I do with an SSD is turn down "swappiness" to a 
minimum.

In /etc/sysctl.d/custom.conf

I put the following lines:

vm.swappiness = 0
vm.vfs_cache_pressure = 40
vm.dirty_background_ratio = 10
vm.dirty_ratio = 40

There are also a bunch of networking defaults for IPv4 and v6 for 
security and simplicity, but this is about SSD wear and swap space. A 
swap partition that is simply never written to never wears out.

I also put in ramdisk options for /tmp in /etc/fstab in order to 
reduce disk writes.

You mean tmpfs, not ramdisk. Nobody sane would prefer ramdisk over tmpfs 
for /tmp.
