Like a lot of things in GURPS, it looks intimidating at first, but don't be thrown by it. In my experience, you can mostly get away with eyeballing or approximating a lot of things in the translation between editions.

Hell, you could even have NPCs (or PCs, if you want), creatures, powers, whatever still use 3rd rules and mix with 4th rules.

Some books will be harder to use than others. The details about how combat works have changed; particularly notable are changes to how active defenses are calculated when used in conjunction with armor and advanced combat options, making 3rd Martial Arts a challenge to utilize. Also, the power systems from 3rd Supers and Psionics have changed completely, but both still have cool ideas.
That one is pretty much a wash, but that book is a monster so many people didn't use it in 3rd. Again, those you could probably port over any or all of these rules if you're willing to deal with the added bookkeeping. It should work, as long as you are willing to justify the differences between some characters functioning one way and other characters functioning another, and as long as you can maintain a kind of consistency, even if it's consistency within just those select characters.
