So, I want to be able to activate a redstone signal using a command block, but from way across the map. How can I do this?

When using coordinates, you need to specify a radius so that it knows how far to search from that specific point. Try changing your command to:
/testfor @a[x=-611,y=80,z=714,r=1]
You can also compact it down into:
/testfor @a[-611,80,714,1]
I believe that the reason is that without a radius the selector makes no sense, so it is simply ignored and tests for @a.
Place a command block with the /testfor @p[whatever] command.
Then, a redstone comparator facing outwards from the command block.
From there, place your redstone or any redstone contraption that needs the input.
Note: If the comparator's signal isn't strong enough (1 block worth of power), place a Redstone Repeater after the comparator and any output should now have 15 strength.

Use
/setblock. For example:The left command block is whatever you want to put in it. For my example, I used
(This command tests if anybody is online...pretty simple).
The right command block is
Replace x,y, and z with whatever the coordinates are next to your redstone dust. So, I put a torch next to the left command block. It gets powered, makes a signal, powers the
setblockcommand block, that command blocks sets a redstone block next to the redstone dust, and viola.
