I tend to agree - if you're really interested in climbing better, you need more muscle and less dead weight on the engine. Wheels won't make much difference. Check out the TDF climbs on DVD - look at what they're riding. Fairly plain wheels, no aero rims. Arguably, tubulars might help a bit, as you can pump them to higher pressures. Bit of a pain to repair punctures, but it's like climbing - you have to welcome pain to get better.
However, if you just want better wheels and can spend the bucks, here are the four I have had personal experience with:
Rolf Vector Pro. Fairly cheap on the market these days ($200-300 on ebay). About the performance equivalent of Kysrium SL's, without the big name. Very low spoke count, medium aero rim. Stiff as all get out. Takes a trained mechanic to true them, but in two years of riding, mine never needed truing. Tough wheels. Fast on the downhills and flats. Drawback - harsh ride.
Campy Zonda G3. Moderate aero rim. Similar to the Rolfs in aero, but smoother ride, due to less radical spoking. I paid $350 for mine at cbike.com, they put the Zondas on sale every so often. These are pretty much the Eurus wheels without the Record hubs. The Zondas are my normal riding wheel these days. Good looking wheels, too - black rims with silver lettering. If you get them, get on ebay and find a set of used Rolf titanium skewers - the stock Campy skewers weigh a ton.
Zipp 404. Bought mine used last fall on ebay, when the other bidders fell asleep and I got them (relatively) cheap. What can I say - deep carbon aero rim, moderate spoking. Very light, very aero, I'm averaging 1-2mph faster on the downhills than the Rolfs. Very smooth ride. Downside - the rims can be a bit fragile, so you don't want to riding over railroad tracks on them. And, Zipps are sinfully expensive. $1000-1400 a set if you buy them new. Don't buy them in clincher - it defeats the purpose of shelling out all that money.
Campy Nuovo Record hubs/Arc-en-Ciel rims. On my 70's racer. Hubs still smooth after 30 years. Wonderful ride, they really soak up the road vibration. Pump the tubulars up to 140, and they're great climbing wheels.
If I had to recommend a set, I'd say the Zondas, or if you got the dough, Eurus. Or if you really have the dough, Campy Boras. A mere pittance, at around $3k for a set.
