BPEL on IBM developerWorks website
IBM has been an advocate of BPEL since the beginning, and its developerWorks site has a number of pre-existing articles and tutorials that discuss BPEL and various IBM tools and technologies.
Please note that even though several of these articles are only a couple months old, both the products and standards mentioned may have newer revisions. Please check both IBM product versions and BPEL standards versions.
