Sammerdog - what's your TV model out of curiousity? The whole cable-ready bit has me curious.
Things are straightening out. Audio and video can be transmitted either analog or digital. Digital transmissions can either be encoded (and possibly encrypted) data or essentially raw.
RG6 coax (not older RG59) is fine for transmitting ENCODED digital HD content throughout a house from either satellite dishes or a cable TV feed or an OTA attenna. It can also handle RAW analog SD content (old analog cable, output from any analog SD coax device). It is not used to transmit raw digital HD video data to an output device.
An encoded digital signal has to be decoded. If it's not encrypted then it's just a matter of the target device having the right decoder/tuner. Most recent digital TVs can handle decoding an OTA encoded digital signal directly. So they can be driven right off of the RG6 if you are set up with an OTA antenna.
But if it's encrypted (satellite TV and most if not all HD cable) then special hardware is needed to handle the encryption (typically a CableCard for cable or some kind of access card for Sat). Most TVs do NOT support these kind of cards meaning that some kind of settop box will be needed regardless of TV claims of DCR, etc. The set top box should definitely have a coax input for the encoded signal but you won't want to output using coax for the raw signal to the display device. It won't be HD if you use such and output. HDMI (digital audio+video) or component plus digital audio via either digital coax (basically something like RG6 with RCA connectors) or optical fiber connections is ideal to your TV and/or receiver.
Running cable for satellite is a bit more complicated as you may need a multiswitch to feed multiple drops from one dish (versus cable / antenna where the cables for all runs are just connected with a simple splitter). You still only need one RG6 from the multiswitch to each of your drops but you probably need several RG6 feeds (4 is ideal last time I messed with satellite; I don't know if any of the new dishes need more) to your multiswitch.
