I don't mind a bit, but you might not like my answer.
Honestly, a lot of what you are going to read will be somewhere between a slight distortion of otherwise sound information, an infomercial, and total unmitigated bull****. I can say there are a few people I would look up.
You already have the best book that can be had, IMO. Read it again ten times. Steve Quinn of In-Fisherman fame is a fisheries biologist. He is a pretty straight shooter, despite being associated with In-Fisherman. In-Fisherman is a place to get good information, but you have to have your mental add blocker software engaged. They are basically funded by Normark and Pure Fishing, two of the biggest names in fishing tackle. Still, they are one of the only sources for (often) factually accurate information on biology. I am in the "know your opponent" camp, and consider biological information to be one of the most important pieces of the puzzle. Lures and techniques may come and go, but a bass will always be a bass.
Larry Larsen is a good source. Good sound information, never trying to sell you anything. Mostly magazine articles, but wrote some books too. He is still alive, and is very focused on peacock bass these days.
Rich Zaleski is a source I would credit as being practical and informative.
Doug Hannon made some good observations, but I would caution you that like Bill Murphy, he operated in a microcosm of his unique geographical circumstances. He was a Florida expert, both the fish (Florida strain largemouth) and the state. I'm not trying to take anything away from Doug Hannon, he was remarkably good at what he did, but what he did was very specific. He was fishing for Florida strain bass in their native range, in mostly natural river systems, and as far from people as he could get. He was fishing for "primordial bass" if you want to look at it that way. Very different than the conditions faced by most anglers. Still, read his book "Big Bass Magic"
If you can somehow stand the waves of self-congratulatory stench wafting off of it, "Big Bass Zone" by Bill Siemantel (although mostly written by Michael Jones) does manage to shed light onto effective big bait presentations, something Murphy's book largely failed to do owing to its date of publication. I know Bill was fishing swimbaits towards the end of his life, but he was still in the process of exploring their potential when The Scourge took him.
Other than that... read scientific literature. Find papers published by universities. Read all you can about the things bass eat. Learn a lot about bluegill, and you will know a lot about bass. They evolved together, and are what they are today because of the existence of the other. Learn about crawfish. Get an aquarium, catch the smallest bass you can, bass fry, and raise them. That may or may not be legal, strictly speaking, but do it, hypothetically, of course. I have (hypothetically) raised many young bass, and learned a lot from observing them in different developmental stages. Plus, if they are chilling out, then suddenly become agitated and active for no discernible reason, stop whatever you are doing and GO FISH. Trust me here.
Lastly, some practical advise on the nuts and bolts of this stuff. Practice your casting. I know, I know... you are already pretty good. Get stupid good, Terminator level, robotic death machine from the future level good at it. That mechanical ability with a rod and reel is one of the biggest things that separates good weekend anglers and touring professionals. Watch some BASS tournaments with the sound muted. You don't need to hear anything those guys are saying, trust me. You need to watch their movements and learn. That is the edge they possess, not whatever gear they are selling.
