I'm studying for the VCAP5-DCA exam but most of the hands on labs are using 5.5 or 5.1. and I do have my own home lab with 5.0 that I'm also practicing on. I think it is useful for me to do the labs since it gives me more experience working with VMware even though it's not using 5.0 which is what the exam is on. My thinking behind this is the more labs I do no matter which version gives me more experience, making it easier to find a job in Chicago where I live using VMware.
