My question involves criminal law for the state of: Minnesota

My name is Jay. New to forum. I am a intelligent patriotic American! In 1997 I was charged and convicted of criminal sexual conduct by a jury. After my non paid government attorney did nothing I went to prison for four years. I was young and dumb. I have been on parole for nine years. The case is interesting to say the least.
what I really need is after nine years a new county supervising staff is being jerks and I have a violation for refusing a home visit. It my first one I'm 9 years. I've done it right and am a success story. But I am stiffled by the stigma.
At this hearing can I petion the court on several things?
1. For a continuance on the hearing request my file and have time to either secure council or prepare defense of violation.
2. Motion to be released from parole(I think I have an excellent record to argue for this if possible)
3. Motion to have record sealed or exponged so I can further my career or get one.
I do feel this case has many unique qualifiers on these matters any help would be great. I have a wife and four kids who are a and b honor roll. They deserve better!
