vibration with "thump, thump, thump" sound

I've been researching this, but don't seem to see a discussion matching my symptoms. I'm a noob when it comes to car work, but learning fast.

Anyway, on heavy acceleration in 1st, 2nd and sometimes 3rd I get a vibration and sound from what sounds like right underneath the center armrest. It's related to RPM, and comes around 2900'ish and then again at 3700'ish. THere is a very solid rumbling type sound accompanying it.

Like I said, I'm a noob when it comes to this stuff, I'm hoping someone can say oh yea, that your U-joints or something.
