Good info! Also keep in mind that CHIRP has several ways to lookup/add frequencies.
Under "File"; "Open Stock Config"; you will find lists of common frequencies, including FRS, GMRS, and Ham Calling Frequencies, as well as Marine, MURS, and NOAA weather.
Once you either have a file downloaded from your radio, and/or have started a custom file, you can go under "Radio" and choose "Import from Data Source" or "Query Data Source". Some of these are subscription services, I keep one at Radioreference, it's a really easy way to add frequencies by County, State, Band, etc. I use it if I'm going to be travelling, I'll put the local frequencies I want in the radio (ALWAYS save backups of your files, when you come home you can just reload the channels you originally had.) and move them around in the channels to mirror my trip. I will program an HT for each member of the group so everyone has identical channels to switch to.
For my "standard" files, I will also export a CSV file from CHIRP, open them in Open Office Calc, set them up for printing, and put a hard copy in my CEOI binder in my vehicle and shack. Things happen, and it's nice to have a way to re-enter frequencies if need be, or to synchronize radios with someone who's not normally with your group. Of course, this also requires learning the particular manipulations necessary to manually program a Baofeng (or other radio if someone brings their own).
