Maybe it's out of phase... maybe it's just in a bad location. Try reversing the leads (+ for -) at one end. Try putting it somewhere else in the room.

ebay usually has a ton of resistors, even if you end up ordering 50x the amount you need, since they're usually quite cheap. You could always put the original one back in to test with, and then determine if your swap is what's affecting the sound. With the original resistor, even without the extra bass boost, it should sound pretty normal.
Something like these:

But I'm not sure how many watts yours will need to handle, just do a search for "20k resistor".

Did you ever mention the main speakers you're using? If they're the little guys that came with the HTIB setup maybe your new sub is just way overpowering them. A lot of times the very small sat speakers that come in the sets will not have very good low frequency extension, and that might be why you aren't hearing any presence in the upper bass.
You shouldn't need a new receiver, since any modern receiver should do a good job in a starter system. Did you ever find out how to set the crossover point? There's no online manual at the Sony site, so I'm just guessing here, but there has to be SOME kind of settings for either "speaker size", "LFE crossover frequency", "LFE mode"... anything like that. If possible, you want to set the LPF on the receiver higher, or the speakers to "small". Make sure the crossover on the plate amp is wide open (set as high as it can go) or disabled.
Can you test by putting a different pair of larger speakers as the mains? Either from another setup, or borrowed from a friend or something?

OK, it sounds like we might have it figured out here. If that receiver was designed specifically to work with the little speakers and sub it came with, and won’t allow any sort of adjustments, I think Brent is right. Your mains (the Polks) aren’t getting a full range signal, or even close to it. They’re probably being cut off somewhere around 200Hz, which is why you’re not getting any mid or upper bass from them.
The sub amp may be crossing over at a lower frequency (I think it ranges from 50 - 150Hz or so if you have the LPF engaged), which leaves you with a big hole where no sound is allowed in either the sub or the mains. The sound you are missing would usually be filled in by your mains, but the receiver won’t let them play it in this case.
If you can defeat the crossover on the BASH, you may be able to get that sound back, and it will play through the sub. Not ideal, but it should at least give you a little bit “fuller” sound.
I think the only real problem is that the receiver has the fixed crossover that is too high to use with bigger speakers. Your Shiva should play fine, if it were getting the right signal fed to it (at least that’s my take on it so far).
