Getting Certified with CCNP and MCSE 2003

I have a question regarding these certifications.

Currently, I have an expired CCNA and I know you can renew your certification by taking another Cisco exam. I am going to take 642-811 has anyone taken the exam. Does it have more interaction exams like the CCNA. What would be a good study guide. Any suggestions on achieving the CCNP.

Also, I am currently MCSA 2000, I would like to get MCSE 2003. Does my MCSA 2000 certification count towards my MCSE 2003. Any suggestions on what exam to take.

THanks,
