Is there any kind of productive cobblestone sink aside from transmutating it all?
The easiest things to use cobblestone for are sand, gravel, smooth stone, smooth stone bricks, cracked smooth stone bricks, and scrap. I'd suggest you get at least a few normal barrels (or one extradimensional barrel) of sand, gravel, and smooth stone before you start turning it into scrap.
Scrap, of course, can then be used to make scrapboxes for a wonderful Craftsmas, and both can be used in a matter fabricator for UU matter.
How did you drive the Filter? A Timer? What speed setting? It seems to me that a fast setting will handle lots of different item types coming in, whereas a slower speed will reduce the number of entities by increasing stack size.
Filters don't need a redstone signal to work for this.
Has anyone come up with a faster way of getting quarry output sorted, once a quarry outpaces an RP2 sorter? AE is obviously an option, but the power requirements for replacing my entire RP2 sorting system would be prohibitive. Logistics pipes might also work, but I think even they might clog up and "drip" cobble at the rate my quarry is going.
I was using four filters on a single ender chest by the time I switched from RP2 to logistics pipes. That was able to keep pace with a 50MJ/t quarry easily. From there, I used tubes with filters that branched off to sort out the cobble/dirt/sand/gravel/etc (99% of the junk), and then into a BC pipe system for usage with diamond pipes.

Filters do not need power to filter. They work like one input/one output diamond pipes normally, being able to allow a path for certain things. A example is as follows:
You have a long RP2 tube line running from a filter which is timed (so it will suck out stacks) and sucking from an ender chest into your RP2 tube line.
In the tube line, you have a few filters branching off left, right, up, and down leading into barrel arrays for specific things (I kept it to one type of item per filter, but it should be able to support up to nine types of items per filter). The filters need no activation signal as they're passively filtering.
