For anyone getting a new DSLR already having a few lenses kicking around of whatever vintage is an advantage. I don't know the lenses you list first hand but I think it's okay to admit that they aren't premium optics. That's not to say that they won't take some nice pictures, I am sure they will, and hey, better the lens you have in your bag than the lens you don't own.
A D600 is probably going to get some of the best out of these lenses that they could deliver. Personally I wouldn't hesitate slapping my manual focus glass on any DSLR. You need to add some (non-CPU) lens info in to the body but that's a very easy step.
Ultimately I'm sure if you invest in a D600 you'll want to add some newer glass, but to get started... go for it!
