Out, damn spot! [SLR Camera Cleaning]

Hey guys!
I have a Pentax K100.
I keep the lens caps on when I'm not using it, but I seem to have developed a bit of a recurring problem with a particular spot in my images. It ends up appearing as a fuzzy 'spot' on the images towards the top right quarter.
Thinking it might be some gunk on the lens or whatever, I took the lens piece off the camera body and wiped it down with the camera cleaning stuff I have - a special cloth and solution... but after reattaching it, nothing changed. There's no visible obstructions on the lens anyway.
So, alright, I think to myself. Maybe I have a bit of gunk on the sensor? So I have the camera flip the mirror up, and I use one of those squeezy-ball air pumps to blow any crap that might have been on it off. Still, there's nothing on it.
I fix it all back together, and take a shot, and damnit! It's still got that spot!
I am assuming it is something to do with the lens; the spot in some shots is very in focus, whereas in others it is a bit blurry. There isn't jack that I can see on the lens surfaces, though.
Some examples of the dreaded spot:
Particularly in-focus:
Out of focus:
It's worth mentioning that first shot had about twice as much exposure time as the second, which could also account for why the spot's in focus, which would also not account for the lens being the source of the problem.
It's also obviously not on the backdrop. It appears in other places.
Really, I'm not sure how to find out what's causing it, but it shows up in nearly all of my close-up pictures - pictures of something across the room, it doesn't appear, which suggests to me that it's out of focus enough to be invisible.

If you have a camera store nearby, take it there and try it with another lens to confirm that it's not dust on the sensor. If the senor is fine, there might be some dust inside the lens. The store should probably be able to help with that.

I was just glancing at the sensor with the mirror up and I think I might have spotted the problem - two very, very, very small spots that I almost didn't see in the same position as the spots are in the picture, but upside-down. I grabbed one of those little blower-squeeze-ball things and got rid of them; taking a test picture now to see if it fixed it
For future reference, I suppose I should never touch the sensor?
I didn't, because it's scary and arcane, but I'm just wondering what happens if I can't get crap off it with the hand-blower.
It's never a good idea to randomly touch stuff inside a camera unless you know what you're doing. Unless you don't mind your pictures looking like shit.
Never touch the sensor. You'll just end up making things worse.
A brushless blower is fine for almost everything. If it ever gets to the point where you can't blow the stuff off, take it somewhere to get it cleaned. You can buy special cleaning tools, but they are expensive and not really worth it unless you are a pro who needs to clean the sensor regularly.

In order to clean it ALWAYS take it to be cleaned by a proper place. For example, I have a Canon EOS 400D when I want to get my lenses cleaned i'll send them to a specialist Canon place for the cleaning.

I've got a spare copy of Portal, if anyone wants it message me.
CUZ THERE'S SOMETHING IN THE MIDDLE AND IT'S GIVING ME A RASH
I have a sensor-cover-cleaning kit that's a little plastic wand with special foam tape pads that go on the end. It works great for getting dust off.
