I don't know how this happened, but there's one FAT16 partition in there, which seems ominous. Do I have to start over?

Not sure about Arch.

The Debian distributions have two partitions. A small FAT one to boot from and a larger Linux partition which starts at about 1.9GB in size.

The Linux partition can be optionally enlarged to fill the rest of the SD card.

This is perfectly normal. When you install Arch Linux there's two partitions, one is for boot and the other for storage but not use all SD card space. You can extend the second partition using gparted or similar software.

Lots of tools available to expand the root partition. You can use gparted, but I use fdisk and parted to do that from the command line.

And the fat partition is there on purpose, it comes in very handy for those of us who, on occasion, need to edit configuration files that are in the boot partition, but whose other computers cannot read/write to/from the ext4 root file system. It isn't just Windows that cannot handle ext4, I have two old Linux devices that can only read the Pi's boot partition.

I use GParted (from Debian 7) on my PC directly after copying the Arch image to the SD card in order to resize the partitions on the card.
