As for the left vs. right: I think you can use either one (or use both with a "Y") according to the Polk manual. The volume on the sub has to be cranked up a little higher if you just use one.

The 250 doesn't have an unfiltered "LFE IN", so no matter how you wire it, you going to be running through the variable low-pass filter on the sub.

I have the PSW250, (but not in nearly as an elaborate setup as yours) and I've found I get the best performance out of it by using the speaker-level connections. The old DPL receiver that I'm using it with has a fixed, 200Hz, very gradual roll-off on the sub output, and it sounded terrible hooked up that way.

I didn't study your system layout too carefully, but I'm assuming you're using the 250 as a sub for your surrounds. It might be better, placement-wise, to use the speaker level connetions anyway.
