I would like to keep the documents and pictures folders of my MacMini and my MBA in synch. How can I do this?

If you are comfortable using command line, you can
use rsync which is already available in OSX. Just
Google rsync and you can find lots of references and
examples.
I personally use program called GoodSync that works quite
well.
You can sync folders using iCloud: http://osxdaily.com/2011/11/03/sync-files-between-macs-with-icloud/ although there are alternatives, such as Dropbox. It's best to give a few a try until you find the service that you like the most.
rsync --recursive --times --owner --progress --checksum --delete --dry-run --itemize-changes ~/ORG/ ~/BACKUP should do the job.
This will show what would be transfered (--dry-run and --itemize-changes) by synchronizing everything inside the ORG folder (notice the trailing forward-slash) recursively (--recursive) to the BACKUP folder by comparing files based on checksum (--checksum).
Remove the --checksum option if you want files to be synchronized--much faster--based on modification time and size.
Remove --dry-run for the actual transfer.
man rsync for more information.
