1. Whatever training you take must be delivered either by VMware or a commercial (VATC) or academic (VITA) training partner. You can search here for Install Configure Manage training: http://mylearn.vmware.com/mgrreg/courses.cfm?ui=www_edu&a=one&id_subject=37587
2. I don't know, but you can do a search when you register for the exam here: http://www.pearsonvue.com/vmware
3. The exam cost varies from country to country, and the training cost will be different from provider to provider - the US prices are $225 for the exam (I think) and around $3500 for the training with VMware or a VATC.
4. The exam will retire at some point, but I would expect it to be at least 2014 before it does.
