Hi Lorne,
How do you create these PDFs? If you convert them from applications like MS Word, you can set these options (author, title, description etc.) in MS Word and then convert the document to PDF. Once the settings are saved in MS Word, they will always appear in the PDF Document. This is just an example. You can set these settings in other applications as well. Because each conversion may have different description or title, Adobe Acrobat shouldn't control this. For anything or everything that you do in Adobe Acrobat, for example, signing the document or adding comments to it, information saved under Edit Menu->Preferences->Identity is used.
Apart from this, if you want to modify this metadata after conversion you can go to File Menu-> Document Properties-> Description-> Additional Metadata and Add the information. By Default Acrobat takes the Login Name from the LDAP, thats your login ID.
Answer to your second question is Yes. You can set it to the document (or a bunch of document together). Go to File->Document Properties->Initial View and Select the options under Navigation Tab. If you want to apply these settings to multiple document select this option in Action Wizard and apply the settings to multiple PDFs. To do this, File->Action Wizard->Create New Action->Document Processing->Set Open Options->Click on Options and Set the initial View. then you can run this action on multiple files/folders.
Feel free to write back for more information.
