-I believe all Pana HTIBs suck. I am a fan of Pana product, have a friend who's worked for them for a very long time, etc.
-the only ways to get lossless MULTICHANNEL with movies are HDMI or mch analogs (the bd35 can't). Therefore, you need an HDMI receiver.
-for audio, obtaining lossless movie tracks should be right about at the bottom of your priorities. The differences are subtle, even on very resolving systems like mine. OTOH, differences between room acoustics, speakers, subs, speaker placement, sub placement, listener positioning, treatments, their positioning, adequate amplification, room correction EACH outweigh the importance of lossless HT tracks on their own.
my 2 cents. IOW, you're looking towards lossless for some magical theater pixie dust that's not there, yet are looking at very subpar speakers. Putting top feul into a Yugo does not make it Formula 1. And I already have doubts about lossless HT tracks as really being top feul anyways. The only times I really enjoy lossless, as a large difference, is with classical music bluray discs.
I currently have a Panasonic DMP-BD35 Blu-Ray player and a Toshiba REGZA 37HL67 HDTV. I am currently looking at home theater systems, but have some questions on how to hook them up to ensure I get Lossless audio through my surround system. I've been looking at the the Sony HT-SS2300 because it has multiple HDMI inputs and is within my budget range ($400 or less). So if I hook up all my blu-ray player to the receiver and then my receiver to the tv, I should be able to get the lossless audio right?
Now here is where it gets a little tricky. I would like to get a panasonic home theater system, to match the blu-ray, and the ones CNET recommends here are cheaper too. But they don't have HDMI inputs, would there be any way to hook up my blu-ray to the receiver and still get lossless audio, whether I use an optical digital cable from my blu-ray player to receiver, or if I just hook all my stuff (like blu-ray, and xbox 360) to the tv via hdmi, then run the optical digital cable to my receiver.
