Advice on a first ever Receiver

Hello everyone! I'm completely new here, so hopefully I am in the right section and you can help me!
I've been shopping for my first home theater system for a few weeks now and feel completely lost regarding audio in general and amps in particular. I thought this would be the right place to ask as there seems to be so many knowledgeable people in here!

So I recently bought a

Samsung Es506100
LG BD630

I am planning on eventually setting up a 5.1 system, but I have to start with a 2.0 or 2.1.
Price isn't really a problem, but space is as only denon up to 1913 or maybe 2113ci, sony str dn1030 and marantz slimline will fit with enough room for venting. In terms of speakers, I have no idea of what can be good or what would be a good price point, hoping to go below 500 for the first speakers, but remain open to suggestions!

We have a living room/kitchen/dining open concept, 30x14 feet. The actual living room is 15 x 14. I have to settle with 2.1 max as there is only 3-4 feet of clearance behind the sofa and it actually is part of the hallway.To make the story short, furniture cannot be rearranger for the time being.

I hope I gave you enough but not too much info! So what are your suggestions? Is there anything else I'm missing?

Thanks!

Thank you! I have been looking at the avr-xx12 and avr-xx13 for a day or two and I wondered if the 2113ci wouldn't be too much for what I m going to do with it! Is the sound quality really superior to the 1712 ? I' am starting from scratch and I don't have any legacy devices. I'll be positng in the speaker forum follwoing your suggestion!
