A group study effort is a great idea. When I self studied for CCNP exams I used the Cisco books as the Sybex books are known to have errors and were inconsistent with the exams. Another pointer for you is to not just study for the exams, anyone can pass the tests. Prepare yourselves for the exams yes but also prepare yourselves for the career you plan on taking on after the exams that is the important part. If you guys ever go on to group study for CCIE or Cisco VoIP stuff let me know
