To answer the question for the OP, as far as the actual hardware is concerned, everything is the same (with the exception of the 4G LTE version currently available in Korea). Usually, the differences in other regions are software based. Usually the differences include, but are not limited to, pre-loaded language packs/support, region specific pre-loaded software (like BBC iPlayer for example), etc. Language support usually isn't an issue as this is set up when you initially fire up the device the first time.
Sometimes, other tweaks include slightly different drivers for your modem/radio in order to fine tune it to best take advantage of frequencies used in a particular region.
When you go to About Phone in your settings, your Baseband version refers to your modem/radio/kernel. Build refers to the region specific pre-loaded software and OS version (or the custom ROM you may be running!).
As for the two (as far as I know) different hardware versions of the Note, one supports LTE and the other does not. The HSPA+ version (which is the one I bought off Amazon) features the 1.4 ghz Exynos chip that Samsung makes themselves, whereas the LTE version features a Qualcomm Snapdragon chip at 1.5 ghz (also still backwards compatible with HSPA+ AFAIK).
Even though the Snapdragon chip is clocked faster than the Exynos, a lot of people have argued that the latter is a much superior design. During everyday use, you're not likely to notice much of a difference between the two, but I can say for sure from experience, that the Exynos is a BEAST when it comes to HD video playback and graphics intensive games etc. (Frankly, the fact that the Exynos can outperform Tegra 2 in specifically Tegra designed games with a little tweaking speaks volumes to the prowess of the chip itself)
