Yes it matters, specially on APUs. It's not going to be twice as fast, but it will be faster. Around 10 to 15% faster than single channel.

In theory, dual-channel gives you a combination of twice the bandwidth and half the cache line fill latency. In practice, I do not remember seeing figures about that in a long time but I would expect that to make a 10-15% difference in typical benchmarks, more for graphics-intensive benchmarks on IGP or memory-intensive apps.

Yes, for most applications this is true, mainly because they don't need all the avaliable bandwidth that say 1600MHz CL9 RAM has to offer. Other RAM intensive applications will benefit more from RAM speed. With APU's I'm not too sure how fast your RAM has to be before there is no benefit, but it could be around 2133MHz that the speed has a diminishing return.
Generally, dual channel is recommended, but not required.
