Analog is a bit different. The information sent via analog is more easily corrupted. This is where a monster cable could make the difference. But only if you have a lot of EM interference.

Please tell me you're kidding.
Please? I know it's not April 1 or anything....
No? Damn. OK.
Digital Cables are not DIGITAL. They are very similar to analog audio cables, but often can pass signals at higher frequencies (like some digital signals.) They may also have a tested constant 75 ohm rating. Otherwise, they are pretty much the same as analog. If you need to pass digital signals in a pinch, you can use any cable. It will work. I'm not kidding. You are right in thinking that digital signals are broadcast as 0s and 1s, but don't be fooled that your cable is anything but a piece of wire.
As for analog cables, most cables have some kind of shield to help protect against EMI and the like. Save for Kimber PBJs.....
And yes, these things make more of a difference the more you move up the resolution ladder. A boom box might not show the differences in cables, but a high end rig (or even a mid level system) will spell it out pretty quickly.
So back to the original question: are they worth the money? Some are! Just remember that most tv manufacturers are trying to make money, so they'll include only the most basic junk to get your sound out to your receiver. A simple upgrade to cabling is a good use of money (within reason!)
Me? I run Cardas and Harmonic Technology. Love 'em!
