>> A. Can this be done, will the signal run over a RG6 CoAx cable?
It probably can, but you would do better to use LLC 400 cable, which has a rated response out to 16GHz; I could not find specs for RG6 that go past 1GHz.
Here's a source for LLC-400 - http://www.l-com.com/item.
>> B. How long of a run can you use of the RG6 coax?
1000 foot spools are the longest typically available. 1000' of RG6 has over 36 dB of attenuation at 1GHz (more at higher frequencies, but I cannot find specs above 1GHz).
>> C. What adapters to get and where to get them for USA area?
That depends what equipment you have. Most antennae come with N-female connectors, though it's possible to get some models with other connectors... so you'd likely need N-male connector on 1 end of the pigtail. D-Link equipment typically uses RP-SMA; Linksys typically uses RP-TNC, which is just about twice as big as RP-SMA, but only half as large as N.
Here's a cross-reference to show what most equipment uses - http://www.l-com.com/conte
They also sell connectors there, as well as pre-made pigtails (which I recommend you use) of varying lengths. http://www.l-com.com/produ
Just click the ''Connectors'' link on the left side of the page to get prices on them, but you may find it's almost as cheap to buy a prebuilt cable as it is to buy the connectors and cable separately.
Here's another source for LLC 400 pigtails, btw - http://www.wifi-link.com/p

The impendance of RG6 cable is 75 Ohm, wireless cables uses 50 Ohm. Also the lengh of the cable is relevant. The best result you will get with perfectly adjusted antennas and cables. This may be difficult if you make the cables yourself.
The transformation from 75 to 50 Ohm will produce (smaller) losses, also the cable length as well as the cable lenght factor itself, which should be a multiplicator of the half of the wavelenght. As higher the gain of the antenna, as longer the cable can be. The maximum lenght depends on the antenna gain and the cable quality, maybe 8m, maybe 20m.
The better idea may be to set an Access Point near the antenna and then use a network cable between the AP and the PC. You get a lot of high gain antennas for access points with cables in different lenght.
