Both of which are located on the cpu. I assure you that you are not overclocking your actual northbridge at all. The memory speed is also not technically linked to the HT reference clock. The bios artificially imposes a ratio but they are in fact set separately at the hardware level. This feature can easily be turned off by setting the ratio to "unlinked". This will allow you to raise/lower everything else without effecting the ram speed. The reference clock is linked to the HT controller. But that's also on the cpu.

So yes. The cpu is the only chip effected by the HT reference clock. Unless you count the HT bus controllers on other chips but I don't. Other chips use other clock signals. Which is not very efficient from a design standpoint but it does make OCing more flexible.

With a few exceptions, no. Quite frankly there would be no point in doing so anyways. Everything can either be set independently or has no effect on performance.
