I plan on getting a "Alphacool HF 14 ATI / nVidia Smart Motion Universal VGA Block - Copper Edition" universal GPU water cooler. Does anyone know of any good ram sinks and other sinks to accompany this to cool the other main components on my GPU? I have a pair of 660ti in SLI.

Koolance makes packages of 8 sinks. They are cheap and more than you need. Since you need no cooling at all (can't overvolt the ram). You will already have a VRM heat sink on the card or don't need one. But it is used to having some air go over the top of it. So on my GTX 670 I took a small 80MM fan and attached it to a gelid vga pwm adapter so that the fan speed would go up with the GPU temp. Of course you need to adjust the fan speed ramp so that the fan is running at a decent speed when your GPU gets to about 45C.

You don't have to actively cool the VRM but it is a good idea.
