First, you'll get a lot of insight by defining something simply and looking at the analysis page from solr admin. That's a very valuable page.
To your question: commongrams are "shingles" that work between stopwords and other words. For instance, "this is some text" gets analyzed into this, this_is, is, is_some, some text. Note that the stopwords are the only things that get combined with the text after. NGrams form on letters. It's too long to post the whole thing, but the above phrase gets analyzed as t, h, i, s, th, hi, is, i, s, is, s, o, m, e, so, om, me...... It splits a single token into grams whereas commongrams essentially combines tokens when they're stopwords. Have you looked at "shingles"?
