Water profile can be an important factor in beer quality, especially for particular styles. You should get a municipal water report so you know what you're working with. Looks like Hillsboro is a really small place but if you are on municipal water I bet someone knows what's in it. Otherwise get a water analysis done. Or just brew with RO and add the minerals you want--I just started using the EZ Water Calculator and find it very simple to use. Mineral additions take just a few seconds.
It's true there are lots of other important things to think about when you are a new brewer so getting into water adjustments might be something to put off until later. Having said that, it's a simple thing to do that can help improve your beer.
