As far as wheels and such... after a later-in-the-Series race at Bethel (where I did much better than the earlier races) I compared notes on the finish with a friendly rival competitor. He and I both like the sprint there, we both raced head-to-head there many times, and I rarely beat him. He's a very, very strong rider, uses "practical" equipment (CAAD8 plus carbon aero tubulars). He's a pragmatic racer.
Anyway, on that particular week I improved dramatically in the finish, winning the sprint rather than placing 5th or 8th or whatever. I commented to him that I just got some significantly lighter wheels (DV46 tubulars, versus Eurus clinchers). I made an off-hand comment along the lines of, "I think they made a 20 foot difference in the sprint". He turned to me and said, "I think that's about right. It's the difference between placing and winning this sprint. A lot of guys think we're idiots when we talk like this but we both know this sprint and we know how wheels can affect it." I started noting his wheel choices and started seeing that he's very conscious of what wheelset he runs at races.
Having done that sprint, oh, about 110 times in races, I can vouch for the fact that wheels help me there, given the same bike. The lightest aero wheels are best, seconded by aero wheels (based on speed approaching sprint), followed by light wheels.

All other things being equal, Campagnolo Record or Super Record hubs make wheels fast in my experience. Of course, 105 and Cyclone are the fanciest non-Campy hubs I've run.
If you can send me some 32 hole Dura Ace and Superbe Pro hubs, I'd be happy to run some tests for you.
Oh and whatever the fancy Sram hubs are called. Red, is it?

Well, yeah, but really I'm expecting lower effort at the same pace. 2 bikes set up the same, except one with the Bonti's and the other with handbuilds (Alchemy hubs). My HR is consistently 10-15% higher at the same pace on the Bonti's. I'm expecting that to come back down with the new wheels. If it doesn't, then there may be an alignment issue with the frameset and it isn't the wheels at all.

People buy really expensive cars expecting it to somehow make them a better driver, that doesn't mean it happens.

OMG... I have a set of Race XXX lites sitting in the garage I keep for climbing. Typically, I use Williams System 30s. Note to self...next time riding with women, change to Race XXX lites.

Some expectations are realistic, some are not.

Yes & no or maybe marginally. It seems like many hubs are smooth but the wheels don't necessarily have "kick ass" speed. I have heard hub having high flanges adding some sort of stiffness? Mavic Ksyriums use a Zicral alloy that make them noticeably stiffer than your average wheel. I haven't ridden Zipps or Hed wheels but I'm sure they use their own strategies for achieving power transfer responsiveness...

So are there people arguing that wheels and hubs have little effect or no on overall efficiency?
If so, I find that extremely difficult to believe, just from having a rudimentary understanding of physics...

The point is that even bad hubs aren't that bad. Sort of like how ceramic bearings probably do work better, but marginally at best.
