If not, are there any other applications from OpenOffice, or within OpenOffice 2.3, which allow you to edit PDF files?

I think Adobe is actually quite good about the format and licensing. Some of its PDF variations, such as PDF/X, are open standards.
PDF is an open standard
Anyone may create applications that read and write PDF files without having to pay royalties to Adobe Systems; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.

To accompany the standard format, Adobe created a free viewer to ensure that anybody could view distributed PDF file's freely without requiring the purchase of any additional software - the viewer was made freely available.
To create PDF files the user could purchase Adobe Acrobat from Adobe direct or as the specification of PDF format was freely available to competing software authors - software applications from 3rd parties quickly appeared and this healthy competition along with the stability of a freely available viewer at no cost has ensured that the PDF format has now become 'the' preferred method to share documents between Government agencies, departments privately and for companies large and small.
Everybody was happy, Adobe was the philanthropic author of a world wide standard available to anyone, End users and Suppliers could share all manner of documents and information and there was a healthy 3rd party software community expanding the market and ensuring that inexpensive solutions for creating and manipulating PDF files were available for even the smallest business and private user whilst Adobe remained at the top of the heap providing heavyweight commercial solutions for big business.
And then ... for some reason only known to Adobe, they decided that some functionality would be available to users of their free Adobe Reader only if they used a product officially 'certified' this functionality to do so by Adobe - all competing software applications would now have to apply to Adobe for a certificate or the new functionality would not be possible with files made by competing and 'non' certified PDF creation and manipulation tools.
Suddenly the 'Open' PDF format was not so open and it is our concern that Adobe will continue to extend this in the future to regain some degree of control over who can create software with the ability to offer advanced PDF creation and manipulation functionality - whereas in the past the primary reason for the success of this standard format has been the fact that any software company has been free to create products for the purpose without interference from any party - including Adobe.
And that is why we have taken almost 2 years to create the 'Free' PDF-XChange Viewer to allow PDF files created by any software (not just ours or Adobe's) that adheres to the open PDF format specification as defined by Adobe - to take advantage of these extended features.
