If you think Steroids caused only 1% of the increase in HR's (and runs scored) I think you're drinking your own cool aid.
I am not sure what the million other causes are but the ones you listed are certainly not 99% of the reason.

Now my original point was that the game changed in the late 1990's. We now have more big hits, more walks and K's, less SB.
Now for some opinions....
Now what is the cause of this change?
Could it be a shrinking strike zone? I have no idea. If the strikezone did get smaller, it is hard to explain why strikeouts went up. I actually don't think the strikezone has gotten smaller. When I was a kid (the 80's) the de facto top of the strike zone was the belt. I think we see more "high" strikes today then we did.
Is it smaller parks? This certainly is a major factor. There have been 14 new parks that opened up between 1994 and 2006. Nine of them are more hitter friendly than the previous stadium:
Colorado
Cleveland
Detroit
Houston
Milwaukee
Philadelphia
Pittsburgh
Cincinnati
St. Louis
Four of them are pitcher friendly:
San Diego
Seattle
Arizona
San Francisco
Atlanta is the 14th but it was the launching pad before and it still is.
Is this a factor in increased runs and hits? Sure. Is it significant, I would say so. Is it more than 50% I don't think so.
What about the change in hitters approach? I would say the "Yankee" batting style is a game changer. However, is it a cause or an effect? Walks are certainly less helpful without the big hits (regardless of booger says). The big hits probably cause big swings which probably cause more swings and misses. I don't mean to have circular logic here but now what causes the big hits? I would say PED.
The game changed significantly. Are there lots of causes? Sure. Are steroids one of them? I think so. Are steroids a significant cause. I think so. I just don't see how you can explain such a significant gain in power stats without them. There are similar changes in HRs in baseball's history but there is always a reason (WWII, mound height, ball change), I think this increase, and the 20% decrease in HR's since from 2006 to today has to be partly (and a big part) be explained by steroid use.
