Building a new setup and would like some opinions...

[BryCola]

I just joined this forum, but am a long time lurker. I've read tons of threads about so much stuff that I'm very confused. But instead of asking a million questions, I'll just say what I've decided to do and see what y'all think. For a TV, I've decided on the Panasonic TH-50PZ800U. I could go a little cheaper and get the TH-50PZ80U, but reading this forum made me think I should go with the new 800 model. Do y'all think this is a good move?

As for a receiver, I've decided on the Onkyo TXSR805. Here's my main receiver question. I want to keep my current speakers...they're Klipsch and about 4 years old. I only have 5 speakers and the subwoofer...and the 805 is a 7.1 system. I apologize if this is a stupid question, but is it ok to use my 5.1 speakers on a 7.1 receiver? Is there a setting that makes it a 5.1?

Thanks so much for any info.
