Thank you very much for the replies, guys. And thank you for welcoming me so warmly.
The purpose of this system will be playing music from my phone and watching movies.
I researched about amp, preamp, integrated amp, and receiver because I was still not clear on the differences. Based on what I've read, an audio receiver is capable of powering the speakers and receive inputs from external devices. If this is correct, this is exactly what I need. And wvu80's recommendation looks like it will be a great match to RP-160. And I wanted to additionally purchase R-12SWI subwoofer and it looks like I can do that on the Yamaha RX-V659, which I am really excited about. Since it is an wireless subwoofer and has a built in amplifier, I can connect the trasmitter that comes with the woofer and plug it into pre out of the Yamaha receiver. Is that correct?

For brians7's recommended Adcom GFA-535, can I use this 3.5MM STEREO MALE TO 2 RCA MALES to connect it to my phone and play music from there? The reviews look great but this one does not seem to have LFE out. So I guess if I were to use this amplifier, I would not be able to use R-10SW sub?
