Would this be a working RF-603 setup?

Well you YN-560 does have a sync port should work find from the pc cable. All 4 methods should work fine buddy, although if you need that much light (Unless you are getting all artistic) maybe look at other portable options.

What you have illustrated will work in a round about way but without getting my gear out and trying different methods it's difficult to be 100% sure of the results.

Your website links are not working.

I would consider anything over 2 meters long. The electrical interface in the device has a specification, but because this is down and dirty consumer stuff, there will never be any written documentation. My statement on the length of the cable is my opinion (based on a season or two of design experience).

Hope this helps,

There is no high frequency signal being passed through the sync cable, just plain ole DC voltage, so the length of the PC sync cable shouldn't really be of concern as long as we're not talking about a cable that's a mile long (exaggeration, of course).

The high frequency signal is the transition from one state to another. The length of the cable will degrade the transition so instead of a nice clean transition from high to low or low to high, there is a gradual ramp at the far end which wreaks havoc with the input circuit at the end of the cable.

Yes, but for the lengths of PC cables we're talking about, that will not be an issue.
