I think if you can just skip the ECR check category then your required documents become just (as per http://passportindia.gov.in/AppOnlineProject/docAdvisor/attachmentAdvFresh)
If you go through this route and if you want to be in NON ECR category then you get into Matric Certificate as a requirement which may become an issue for you. I am not sure if having that ECR stamp is a big problem, if it is then you need to go through a long route. If you are planning to go outside India immediately and want NON ECR status for some reason then its an issue.
