Yes! Your 'laying pavers' process matches what we did to a "T". Base of 50:50 dust and stone whacked - engine driven whacker, spread with a mix of stone dust, sand, and around the edges , a small amount of cement. This mix is screeded in front of each row of pavers, and bedded down with a rubber mallet and a length of 'four by two' timber.
Currently to the last stage you mention, polymeric sand to be swept into the joints, but it is raining, so some other finer day!
