Let me know...I'm thinking in a couple weeks
HDMI 1.3 and audio - do I need that?

You have to have an HDMI audio input... HDMI 1.1 minimum which I think is any a/v receiver with an HDMI audio input.. Rodolfo does a great breakdown...Does this mean that to obtain either:-
1) Dolby Digital Plus
2) Dolby TrueHD and
3) DTS-HD
HDMI Part 5 - Audio in HDMI Versions
You canIs there a guide line to compare how much money I would have to spend on an AVR with HDMI 1.3 to match the HD sound, which I can get from my Denon AVR-2802?

The new codecs are DESIGNED to work without loss of quality across an HDMI V1.1 link when the player does the decoding. There is no reduction in quality implemented by the player or codec if it discovers the link is V1.1 instead of V1.3. The multiple channels of PCM that come across the V1.1 link are the best the new codecs can produce.
Period.
The only thing that V1.3 adds is the ability to send the original, undecoded bitstream format to the receiver for the receiver to decode. Your ability to actually take advantage of this may be limited however. Discs authored in the "advanced content" mode *MUST* be decoded in the player. Most commercial discs are authored this way. The net result is that even with a V1.3 link, and a new receiver with its own decoder for that codec, the decoding still must happen IN THE PLAYER and what comes across the V1.3 link is identical in quality to what would come across a V1.1 link.
Even if decoding does happen in the receiver, what comes out of the codec itself is still the same quality. This is true even if the receiver has a higher internal sampling rate. Such upsampling (which can be applied just as well to a signal coming across the link as PCM) helps insure quality of subsequent processing inside the receiver, but the information coming out of the codec is identical either way.
