The supercomputer I am researching has 2.2 petaflops and boasts total memory of 1000 terabytes and disk space of 23.5 petabytes.
Is this more computing power than the total of the entire worlds computing power 10 years ago (2004)?

No, and not by a long way.
Take 25,000,000 ordinary desktop PCs from 2004. To exceed the supercomputer you're talking about, each would need an 88megaflop CPU, 40Mb of memory and a 940Mb hard disk. In 2004, CPU clock frequencies were already in the GHz range, RAM in the hundreds of megabytes and hard drives in the gigabyte range. And there were many more than 25,000,000 computers in the USA, let alone the world.
EDIT: I realize my answer is a bit off-topic, but I let it anyway, it could interest the OP.
I cannot tell you if the most powerful supercomputer today is more powerful than the sum of all computers 10 years ago (I don't think so), but I can tell you that the most powerful supercomputer today is about 30 times more powerful than the sum of the best 500 supercomputers in the world 10 years ago: http://top500.org/statistics/perfdevel/
Here's another way to think about it that might help your intuition a bit. Moore's Law states that transistor density double every 1 to 2 years (you'll find varying numbers here). Let's be optimistic and assume that this correlates to a doubling of computing power every year. In 10 years we should expect supercomputers to be roughly $2^{10}$ (1024) times as powerful as they are now.
