The papers that you originally filed should have had the request in them. You can try to amend the filing, or you can try to ask the judge to do so at the time of the hearing. Any award of court costs is purely at the discretion of the judge.
You cannot divide what is not legally yours. Nonetheless, the court ordered you to do so. I would therefore suggest that you contact an attorney to "clean up" the language. Since the shares cannot be divided now, and quite possibly the company will not divide them in the future, the language in your Decree needs to reflect your duty to protect your ex-wife's interest, and to get her the money and/or stock that she is entitled to at the correct time.
The issue is probably of medical necessity. Your decree should define your requirement, however, in almost all cases, elective or cosmetic procedures will be excluded.
If constant filings are an abuse of the system, the court can require a party to submit pleadings before they are filed so that the court can rule on the issue of whether or not the "abusing party" can go forward. This is very rare as there is a presumptive right to be able to file most anything.
If the "restitution" is for child support, then absolutely file for contempt. The court has a great deal of power, and many tools, to enforce support orders. The Maricopa County Superior Court website has a Self Help page to assist you in filing on your own.

When a party continues to abuse the system, and will not comply with court orders, the court can direct the Clerk to not accept any new filings from the abusive party until the judge has...
I believe that you should contact a competent family law attorney to advise you as to the reasons to seek all available remedies versus settling quickly. It appears that you have several legal remedies that you could seek, however, a great deal of balance between risk/reward, benefit/detriment, and such must be made. The simple answer is to cut and run, but you may be leaving too much on the table. While getting out quickly has its merit, you should make that decision only after you have all...
If the decree is already entered, and you may be able to amend or modify the terms in very limited areas and under very limited circumstances. If the decree has not been entered, those payments can be ordered or agreed to under some conditions. You should speak to an attorney for more precise help.
If you are looking for grounds to dissolve the marriage (divorce), it does not matter. Unless you have a covenant marriage, fault or reason does not matter. If you are trying to void the marriage, a different set of standards apply, and the analysis is very fact-driven. You should contact an attorney for guidance if that is the case.
