If you are just going to run two floor speakers in lieu of the full 5.1/7.1 set up, I recommended buying a receiver that allows you to bi-amp the front speaker for more power to utilize the power of those unused channels. And if you get a 5.1/7.1 w/sub speaker package down the road you can just set the mains back to the front L/R.
I've had experience with Yamaha, Sony, and Onkyo AVRs. I always recommend Onkyo, which has excellent quality in their entry level gear and their THX2 Select reference gear is up there with Marantz. Tip: Don't use speaker wire any smaller than 16 gauge. I use Monster XP. I use to be a Sony guy myself before I stumbled across Onkyo gear.
However, for an entry level HT set up, there is nothing wrong with the gear in your links.
