As for the cloning theme throughout, I think it's an excellent idea. As pointed out, there are ways in which our technology is more advanced than that of the Star Wars universe. Moreover, every bit of evidence is given in the PT and EU (for what that's worth to anyone) that perfecting the art has been difficult. Our earthly cloning is a laborious process. It requires the tedious removal of genetic material from an existing ovum, inserting DNA from the prospective cloned creature into the new ovum, placing that ovum into the uterus of a living creature of the same species, hoping implants and grows to term. If the creature is successfully born, there still remain some faults that result in reduced health and a shortened lifespan due to improper gene expression over time. As a result, cloning is still quite imperfect, and may remain that way for quite some time. Imagine how the Kaminoans have overcome that, dramatically increased the rate of growth during incubation, programmed personalities and vast knowledge into those brains, and have done so with a fiscally responsible success rate (check out the failure rate for Dolly the sheep: she represents 0.36% of attempts--the only success!). I think an entire race of clones could prove quite valuable, indicative of a technology worth stealing in preparation for war!
