Speaker wire would probably be your best bet. For line level audio, you'd need them to be balanced, which can be expensive. I doubt you'd get the coax digital that far without alot of defects. You'd need an inline repeater to get the optical digital that far. You could also combine the audio and video using a modulator and run it all on a coax cable.
What's the best way to provide the audio that accompanies the video signal at 130ft?
I recommend using digital coax. I have done this for an approx. 85 ft. run using standard RG6 coax with F to RCA connectors with good results. I think I've read of others going longer than that, so 130 ft. should work ok. Good luck.
I have multiple long runs of component video my longest is ~120 feet.
Regarding the second question on audio, I think your best bet is to use digital audio over coax, that is what I do and I go over 120 with this too. If your equipment does not have a coax output for audio you can pick up a spdif/toslink to coax converter up at radio shack for a few bucks. It has been my experience that the you can run the digital audio over most high bandwidth video distribution amps, switches and matrix switchers. If you use a RGBs or RGBHV type switch or amp just run the digital audio over the sync ports.

I agree with Jay. I have used RG-6 coax with twist on connectors to F adapters for component and video cables and it works great. Go for it and save yourself a bundle. Just keep in mind that the RG-6 is larger and a lot less flexible than speaker wire. I also use different color Sharpies to color code the coax.
