No, we are not talking about different SW. Acrobat, Photoshop, Dreamweaver, AE, Premiere, Flash, etc are all part of a set they call the "Creative Suite." It is currently at CS 4 (though 5 is supposedly due early this year.) These can be sold together in the Master Collection, subsets like the Design set, or sold one by one for any given piece of SW, such as Acrobat or Photoshop. And then there are the free (and necessary, in some cases) tools, like Acrobat Reader, Flash Player, Adobe Media Player.
Generally speaking, for some of the people who are not that SW savvy: You usually can use a couple of rev's back without issue on newer computers, but there are sometimes issues that remain unaddressed as the company has abandoned support of the product for a newer version. Whether it will work and how well it will work? Look up issues online before you buy. If someone is giving it to you, or you have it already, then try and see how well it works. Nothing lost there, except sometimes, huge amounts of time and your temper. :-)
But some of these releases (including CS4) had/have specific requirements for RAM and processors that you may or may not have. Always check the tech specs.
As to free or cheap tools to edit pdfs, this article is really helpful:
