No one can answer this question properly without knowing specific facts of your case and what criminal history you have (I would suggest you not share that here).
It is always in your best interest to have an attorney. If you cannot afford an attorney you should accept the court appointed attorney to help you with the case. They can get information and speak to the court and the district attorney when you cannot.
Your question is vague. What was dismissed? A charge against you or the order of family protection? Even if a charge is dismissed a protection order may still be in effect until the court modifies it. If you entered the courtroom (before anything was dismissed) with the protected person, knowing she was protected by an order you violated the order.
Attorneys can charge whatever rate they they want - you have a choice to decline to pay that rate and find someone else. It is important that you trust your attorney. If you feel that he/she is lying to you that is not the start of a good attorney-client relationship.
Breaking and entering is also referred to as burglary. Burglary is defined as entry into a dwelling with the intent to commit a felony or theft. You must intend to steal something or commit a felony prior to your entry. So the simple answer is no - it is not a breaking and entering crime. I would suggest that you and your roommate create a written agreement pertaining to your expectations of each other.
The court takes other factors into consideration when issuing a protective order. Among those factors is not necessarily whether charges are filed. The order is issued for protection against potential harm so the judge takes facts provided to him/her into account when issue the protective order.
The court should have advised you during your sentencing about where to enroll in classes and what the expectations were for completion of your program. In Tulare County the court actually orders enrollment into a specific program.
