Dual Channel are 2 sticks usually from the same batch that have been tested to work great together. Nothing special just garanteed to work in dual channel.

C2 means CAS2 wich is usually the fastest DDR400 ram youll find. C2 sticks can have different timmings 2-2-2-5. 2-2-2-6, 2-3-3-6 these all are considerd C2.

C3 is slower than C2, it has timming that can look like 3-3-3-8 or 3-4-4-8.

LL is a marketing term(used by corsair) for Low Latencies, what timming these sticks have depends on their speed. A DDR500 stick could be considered LL at 2.5-3-3-7 while a DDR400 LL stick would probly have 2-2-2-5 timmings.

What does it means and whats the performance difference?

"LL" is basically a marketing term. Means Low Latencies (or tighter timings meaning faster ram)

C2 memory. Means CAS 2.0 timing. This w/b faster than CAS 3.0

What memory type is better for Intel or AMD? Not quite sure what you mean, they often use the same brands/type, depends on the cpu. My understanding though, is that Intel benefits more from faster ram/higher bandwith than amd due to chip architecure.

Nothing that complicated. RAM is often called Cas2 even when it isn't really completely Cas2. It can run timings of 2-3-3-8 and still be called Cas2. For PC3200, LL usually has timings of 2-2-2-5 or 2-2-2-6.
