Hi prathbun, and welcome to OSM!
Please be careful with the sources you use - Yahoo! and Bing have given a specific license to OSM to use their imagery, however Google has not and should _not_ be used. Doing so could pollute the open status of OSM and prevent re-use of the resulting map.
There's lots of information in the Wiki, and don't be put off by the legal bits. Pick a nice sunny day and get the GPS out yourself - it's amazing how many mistakes you'll find in so-called professional maps!

Another thing is road names, more often then not national and state highways are missnamed, in Oregon they are Oregon Route XX, national names are
United States Route XX
This wiki page has a lot of info;
