If, as you state, you sit very close and don't need anything real powerful, then there is no absolute necessity for the Klipsch solution. Lots of other options out there.
If you can't take the time to demo speakers, then can you order a few sets from Crutchfield and at least have a few choices you can hear and choose between? Pick any three bookshelf sets, demo them all and choose one. Fill out the rest of your set with that brand and ship the other two back. This is a far better option than buying any speaker unheard. BTW, it only costs $10 in return shipping for bookshelf speakers, and less than that if you keep a pair, so basically zero outlay for peace of mind.
Perhaps add a set from one of the online purveyors. RSL has the CG5/25 (or 3/23) and free return shipping.
If you are serious about ELAC, the new Debut Reference has gotten rave reviews, but not available at Crutchfield, so you'll have to find another source (BB?).
As to a sub, there is zero reason to keep to the same brand. There will be no compatibility issues with which to be concerned. Choose from HSU, Rythmik, RSL, SVS, as online retailers give you a lot more sub for the money.
For a receiver, stick with Yamaha, Denon, or Marantz in the big brand / reasonable price category
It's a VIRTUAL channel unless stated otherwise.
