Darn it, missed that it was a simple IRA. So disregard what I said about the fees/terrible company stuff. If you're acting as a small business, you're gonna get charged fees for that; it's the end user side I'm used to.
So yeah, stick with Vanguard, likely stay with the target date funds since they're a good deal for now, wait til you build up more and when you add in a taxable account you should likely pay attention to tax efficiency of any funds you choose to hold in there, but otherwise disregard the other stuff I mentioned since it is based off of my experience of being an individual and not running your own business (which I have no experience/knowledge of).
