hey todd, the setup you're using is usually called a suicide hub, and it's recommended that you run brakes if you're not using a hub w/ a reverse threaded lockring.
red loctite will make things a little more secure, but makes getting the cog off again a bit of a hassle.
in my experience, as long as the chainline is within a couple of mm, you should be ok. (having the chainline dead-on will be quieter and easier on your equipment though. sheldownbrown.com has a bunch of good articles on chainline, and fixed gears in general).
finally, the cog is most likely 1/8" wide, so you'll need a chain that fits that. (you can run a 1/8" chain on a 3/32" chainring, it's just a bit noisier than it would be otherwise).
