So, a slower AMD runs just as fast, as a Intel, and costs considerably less.
I happen to know at least 5 people with a AMD chip that is supposed to be clocked at 1.6 Ghz, and constantly overclock them to 2.3 or better. Never a problem, runs cool.

Once again, close but not exactly right. The difference between Intel and AMD is the theoretical amount of instructions each CPU can do per clock. For AMD it's nine. Intel is six. Say for example you are comparing a 3.0ghz Intel to an AMD 64. 3*6=18, 18/9=2. A 2.0ghz AMD would be just about as fast as a 3.0 Intel. That's assuming 100% efficiency and no pipeline stalls.
Is this bad? Not really, they are just designed differently. Intel got a rep for being hot. The new 9XX P-Ds and the upcoming Conroe are just as cool as a comparative AMD. (Actually, I think that Conroe will be cooler)
It's not a stretch to get an A64 to OC to the 2.4-2.7 range. Some go up to 3.0ish. But a comparative Intel will usually clock just as high.
As far as cost, yes the single core A64s are usually the best for the money. But in the dual core field, you can take a P-D 920 and OC it to perform at the same level as an OCed X2 4800. The 920 is considerably less expensive.
AMD does use FSB. The hypertransport is the FSB * the HTT multi. The CPU speed is the FSB * the CPU multi.
Bottom line-Comparable chips from Intel and AMD won't be distingishable without benchmarks. AMD single cores tend to be lower priced than than Intels and vice versa for dual cores.
On your first point, no, AMD 64's do not use FSB technology. You MIGHT see FSB in your bios while adjusting HTT frequency. It is HTT, and should be reffered as such. The clock of the processor is HTT* Multiplier. For instance, my Athlon 64 3000+ is at 244 HTT, and the multiplier is 9. This gives me a clock of about 2.2ghz.
Whoever asked if the extra L2 cache on the Pentium 4's work, in some ways, yes, in some other ways, no. It gives the processor extra high speed memory in lower amounts, giving it an advantage in applications that use the same types of code over and over.
Ok, but it's pretty much the same thing as far as CPUs go. It's the external frequency generated by a chip that the CPU's multi is multiplied by to get the clock frequency.
