Starting system that can grow

[Bad Chile]

First of all - to all the members whose posts I've spent the past five days reading, thank you. I've learned a bunch, and I appreciate it.

I currently live in a rented apartment, have a 47" Philips 47PFL5704D/F7; a Panasonic DMP-BD60K Blu Ray; and no audio system. I'm figuring get a receiver, a Polk CS1 center and Polk Monitor 50 left and right and keep the surrounds (Monitor 30s) in the box until I get a house. Oh yeah, and hold off on the sub until I get the house....

I'm thinking of hitting up NewEgg for the Pioneer VSX-519V-K over the VSX-819V-K. It appears that the Blu Ray player will do all the audio decoding into the Receiver. Is this true? Does the 819 afford me any great advantages given what I know about the DMP-BD60K?

Thank you for all of your time and assistance in helping a n00b? (Ok, way back in 1998 I had a 27" Trinitron, a couple Bose 201s and a VCS-10....all long gone!)

Edit: The only other audio source would be Verizon Fios via HDMI. The TV has 4 HDMI inputs, so I'm not hurting there...

Edit II (for future reference): According to both the Panasonic website and a CNet review, the BD60K does the decoding. "The DMP-BD60 has onboard decoding for Dolby TrueHD and DTS-HD Master Audio Essential. That means it can decode those soundtrack formats so they can be played back on almost every HDMI-capable AV receiver. Bitstream output is also supported, if you'd rather the decoding be done in your AV receiver. (DTS-HD Master Audio Essential differs from standard DTS-HD Master Audio in that it lacks decoding for a few legacy DTS DVD soundtracks formats such as DTS 96/24, ES, ES Matrix, and Neo:6. It still decodes all the high-resolution Blu-ray DTS soundtracks.) "
