That's a long post that's hard to know just what to make of it without some context - how many such mistakes do other teams make? how many mistakes did Stanford make in other years? etc.

I think your conclusion is that mistakes are killing our offense - which certainly appears to be true. Not much more to say there, but below are some responses to small things.

Here are those offensive mistakes: Penalties, followed by sacks and then turnovers—fumbles and interceptions.

Wright chop block negates touchdown pass, results in 3rd and 19

This rather misses your point, but I will use this occasion to maintain that Wright did not make a mistake on that play. Wright made a very good play that is probably exactly as he was taught. Mostly the official made a mistake on that play. To a lesser extent Garnett made a mistake by not leaving his man alone once he had clearly missed him and thus putting the idea of an illegal chop into the official's head.

These stats also highlight that Stanford’s offense played cleanly against ASU,

Which highlights that there can be a big difference between playing cleanly and playing well.

and the defense played very well. 

That would be a "compared to what" situation.

The defense did hold ASU to their pre-UW season low in yards, yds/play, and points [they had fewer in all those categories vs UW]. However, ASU also had the most points anyone has scored against us, second most yards, third most yds/play. More importantly, we had trouble getting them off the field; forcing only 4 punts on 11 drives and allowing 9/19 on third downs and 1/1 on fourth down.

It was a pretty good defensive performance, but probably the poorest of the year (with und the other contender).

This list also suggests the limitations of conventional yards per rush, yards per pass offensive stats.  These stats partly obscure the impact of bad plays—penalties, fumbles, and interceptions—that have resulted in an offense that scores seven fewer points per game than last season.

I don't think they obscure the impact of bad plays, rather they mostly don't address the issue (at least penalties and turnovers). Every stat has limitations, and no stat should be used in isolation to answer broad questions such as "how good is the offense?". If you start with that approach, you're not surprised to find something else that matters.

And for Stanford 2014, mistakes are certainly high on the list of other things that matter.

One more point.  We lost at the University of Dead Fake Girlfriends and at Arizona State, and that reinforces our fears that we are worse at home and may fare even worse in the noise at Autzen.

I am a little confused here, but assume you meant "reinforces our fears that we are worse on the road".

I watched those games, a few times. We have played worse on the road - whether or not we had more penalties and mistake-plays. That's just one aspect of our play.
