I'm getting a lot of spam, perhaps 25 messages/day, and about half of

Care to post the rules hits for some of the FNs? That should be in their headers. That might let is provide more specific advice, for instance: are you hitting URIBL_BLOCKED?

I tried using the "sought" ruleset following instructions from
http://taint.org/2007/08/15/004348a.html, but didn't see much
difference.

Sadly that's gone stale and may not help much with current spam. The last time I saw an update was March 2014.

I'm concerned that the BAYES_* rules aren't showing up in my spam
headers

The two most common causes for that are, insufficient tokens learned and learning under teh wrong user.

Here's the output of sa-learn --dump magic:

0.000          0      15466          0  non-token data: nspam
0.000          0      30317          0  non-token data: nham

You have plenty of tokens, so it's likely you're training Bayes as a different user than SA is running under, and you don't have a site-wide user-independent Bayes configured.

Relatedly, if I create rules for e.g. ATTN, "stock tip",

Funny you should mention that particular one. I just noticed it had popped up to the top of the masscheck corpora hits, and I've pushed a scored rule for it. Hopefully that will start getting points tomorrow.
