Be careful about the binpackages if you add any instruction set optimizations to your make.conf. Trying to install incompatible binaries will wreck your whole day.
Otherwise, I usually just save the world file and any USE flags that I remember setting on purpose. Save copies of the keywords and whatnot, but it's also a good opportunity to clean out the cruft that always slips in over time. Distfiles can be good too so you don't have to download everything again. If you're moving everything to a new computer, you can also just try a straight copy of everything... As long as your instruction sets are compatible it goes pretty quickly. I've got an install that's on its third set of hardware now...

First of all, sorry for the late reply. I had to attend to a course a bit far away from home and it was pretty intense. Now, back home, I'll try the suggestions, thanks! Just for the sake of preventing a future failure, besides personal files (minimum and obvious) the "world" file and the binary packages, built along with the package installation, what else should I backup so that I would be able to quickly restore the same full working Gentoo in a new hardware without having to work from stage3 up? The portage tree is one of those items, for sure. But what else? Thank you all and a good sunday. Francisco
