Is it possible that it's my lens? I just tried the dust alert with my kit lens, and there was dust on the sensor, but a few shakes and it was gone. When I put my other lens (newly bought) on, there was a new speck that refused to move even after multiple dust removal shakes.

Very unlikely. See this: LensRentals.com - Front Element Scratches

Dust on a lens is invisible the vast majority of the time.

Are sensors most perfect on other people's camera or do you just leave it alone unless it gets really bad?

In this picture here, I have one large piece of dust in the lower left corner that is very noticeable. I use the rocket blower but no matter how many times I tried, it will not disappear.

There are also other dust spot as well upon magnification.
I get it 'good enough' and I don't clean unless the spots start showing up in clusters.

Most of the time, there is enough fine detail, and I'm shooting wide enough (f/8 and wider) that the spots aren't even visible. The wider your aperture is, the more diffuse the dust looks, and unless you have large pieces of crap on the sensor or fibers, you won't see it most of the time.

Mmkay. I just went and did it, and it was surprisingly easy (all this stuff about YOU-TOUCH-THE-SENSOR-YOU-DIE made it a bit nerve wracking though ) and it looks like the problem's fixed, not a speck to be found! Much thanks to all your replies (:
