So, I SHOULD NOT use the Pro Logic II, etc. modes for playing back the PCM tracks (of course, by leaving the player on "2-CHANNEL")? Why does the "MULTI CHANNEL" playback mode work better for these uncompressed, etc. tracks?

Multichannel has no processing to the already discrete 5.1 or 7.1 [if present] other then the bass management and time aligment.
DPLII is meant for 2ch sources, so naturally it can't be selected if there are more then 2 ch being present. If there is only 2ch comes in, yes I would use this over "stereo" for movie soundtracks for sure.

Okay, well in that case, I have an "LPF of LFE" selection under the SPEAKER CONFIGURATION menu, which asks you to set the subwoofer's low pass filter; the selections here are for 80Hz, 100Hz and 120Hz...I have it on 100 now, but my other speakers are all set to roll off at 80Hz because they're bookshelves and I would like the sub to handle the bass below this mark. What should the low pass filter be set on here? 80, 100 or 120Hz? I am running a 10" powered Polk sub.

I use the 100hz, it has nothing to do with what sub you're using or how the other filter for bass redirection is set. This is only affects the discrete LFE content, and only it's top end which is brickwalled at 120hz anyway.

I lost you here....I KNOW the player cannot decode ANY MASTER AUDIO at all, yes, I know...so, when playing these tracks, I usually set the "DTS-HD" audio output of the player to BITSTREAM, so the CORE DTS mix is being passed to my receiver bitstream, where it displays "DTS" on the front panel....is this correct? EITHER WAY, am I getting JUST the CORE DTS mix if I bitstream or PCM it with Master Audio tracks?

Use bitstream.

I was informed recently on another site, which confused me beyond belief now, that by keeping the DTS HD audio output of the player set to PCM when playing Master Audio tracks, this is better because the actual HIGH DEFINITION portion of the MA stream is being sent (in other words, the player says "DTS HD MULTI" on its onscreen display when playing Master Audio tracks, perhaps suggesting that the "HD CORE" of the DTS mix is being sent INSTEAD of just the "REGULAR DTS CORE"....is this what is happening, or is the receiver seeing the core DTS mix either way, bitstream or PCM?)

It's rubbish, don't buy it.

THIS is something that probably should have been explained in the manual, for it states this NOWHERE. At any rate, you are saying that the 2-CHANNEL and MULTI CHANNEL speaker setting will not only affect ANALOG OUT, but also HDMI? Jesus...and this was after I was told and was convinced that these settings ONLY affect analog connections....

In theory it shoudn't affect, and if you set everything neutral I.E.multichannel all speakers to "large", subwoofer to "yes" and all speaker trim levels and distance setting left at 0 it will have very little or no affect at all for the HDMI output as far as the how the soundtrack is presented.

I think I saw your thread over AVS. Blue Camry SE?
