Scott, welcome. The M80s should certainly be first(and the 607 would have no difficulty driving them at reasonably high levels). Since the M80s have very good bass on their own, a sub(preferably stronger than the EP125)can be postponed. The M80s can be used to form a "phantom center", so the center speaker can likewise be postponed. The QS8 surrounds add very significantly to the enjoyment of both movies and 2-channel music(when processing such as DPLII is used to extract the natural surround ambience from the front channels and send it to the surrounds where it belongs), so the two QS8s should be included in the first purchase.
Scott, just to add a comment as to power, the maximum rating of a speaker(e.g., 200 watts)indicates what it theoretically could input continually without going up in smoke, but has nothing to do with what it uses in typical listening. The M80s are slightly above average in sensitivity and require less power than many other speakers. For a comfortably loud level 1 watt or a bit less is needed and even on extreme split-second peaks it's unlikely that more than about 100 watts would be required.
