Partitioning and organizing SSD and HDD in a first-time build

Hey everyone!

First post  

I plan on building my own PC for the first time, and I'm trying to figure out the best way to go about organizing my storage. I plan on getting a relatively low-capacity (approx. 32GB) SSD, and a relatively high-capacity (500+GB) standard HDD. I've looked around and it seems like SSD's are awesome in terms of boot times and responsiveness, so I figured it would be a good idea to put Windows (and maybe Ubuntu) on it, and then put my data and files and such on the HDD.

Are there any issues with keeping the OS separate from the rest of the files and data, or this setup in general?

Also, I've seen some stuff talking about how to partition drives; putting the swap file on its own partition, putting the OS on multiple partitions, etc. But I'm not sure how to go about it for this particular setup; so any advice there is greatly appreciated.

And one more thing: I'm currently running Windows 7 Ultimate (64bit) on my laptop, and I'd like to "move" it to the one I'm building. And by that I mean I would remove the OS from my laptop and then install it on the newly-built desktop using the original installation disk/product key. Is this legal/possible?

Thanks in advance for the help.
