      1. I noticed that it seems the form will save in Acrobat Reader 8 and
      not the Reader version 9. Why might this be?




A problem with the system that the IRS is using. They need to update to get it to work.

      2. Can a developer of software freely "redistribute" those forms in a
      software package? In other words, an end user can download the PDF fillable
      forms (such as Form 1040 or perhaps a state form, etc) but can a software
      developer then download those forms and then redistribute them in their
      own software program?




That's between the owner of the forms and the developer.

      3. What is this 500 limit all about? Is it that a form can only be "filled
      out" in the Acrobat Reader 500 times? Or does the 500 apply to something
      else?




You got the first one correct BUT, that only applies to forms created with Acrobat Pro using the newly available enabling features. The IRS for instance, uses LiveCycle Extensions for Reader which uses a server side solution for enabling forms. If you can stay under the 500 limit, you can simply enable the forms using Acrobat Pro.

      4. Where on Adobe's web site can I find this information in their licensing
      agreements?




You'd probably want to give customer service a call. It would be located in the two different product's EULA's which I've never seen on the site (not that they aren't there. I've just never found them.)
