#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
# / was on /dev/sda1 during installation
UUID=a5a945d9-6294-4a0e-b5ac-aa8e75b4e78f / ext4 errors=remount-ro 0 1

Add discard as an option.
so: discard,errors=remount-ro

Before the option "errors" insert the new option "discard".
Options need to be separated by comma.

To remove the swap, you should be able to remove the swap line in fstab, and use a live CD with gparted to combine your swap partition with another partition.

A couple other things you might want to do.

Mount with noatime or relatime.

UUID=a5a945d9-6294-4a0e-b5ac-aa8e75b4e78f / ext4 noatime,discard,errors=remount-ro 0 1

Mount /tmp to RAM. Add this line

none                   /tmp          tmpfs     size=100M  0      0

You can adjust the size depending on how large you want to allow this to get. Obviously dependent on how much RAM you have to spare. Note that this means /tmp will not survive reboots.

Switch to the noop scheduler.

To do so, edit /etc/default/grub, find the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Add elevator=noop

GRUB_CMDLINE_LINUX_DEFAULT="elevator=noop quiet splash"
