Since you have already hired an attorney, it would be best if you were to direct your questions to him/her.
Minnesota allows parties in a divorce to represent themselves Pro Se. Generally this is a poor strategy. The old saying - he who represents himself in court has a fool for a client - holds true. The Pro Se litigant is too close to the case and too emotionally involved to make optimal choices. Also, the Pro Se litigant is expected to know and follow all the court rules and the law - the court is not going to educate you if you don't know how to "play the game" or how the law actually works (has been interpreted by court rulings).
As for your question on maintenance and attorney's fees, the point of an FENE is to give the parties a neutral opinion of the most likely outcome (based on the application of the law to the set of facts presented) should they go to court. I would look to the neutral's opinion on maintenance and attorney's fees as an indication of whether or not a court would award them should your matter go to trial.
My best advice is this - talk to the attorney you have already hired - if you can't/won't work with that attorney, hire one that you can work with. Let him or her know about your concerns and questions and then take his/her advice. If the cost of litigation is a concern, work toward a mutually agreeable settlement (perhaps hire a mediator) rather than battle it out in court.
The proceeding is simply for informational purposes. It does not create an attorney-client relationship.
