I cannot review your documents on this forum - we are a "general legal information" only forum and cannot provide formal legal advice, instruction or counsel.
The "Points and Authorities" for this kind of motion are going to be very short and concise (if you were a party in a case and making a more complex motion, they can run on for many pages), yours might be as short as one or two pages. All you need to do is cite the legal authority giving the court the authority to issue the compensation, and any associated issues.
I would like to provide you with some pointers here, but based on your fact pattern (you have some other parties that went and jumped ahead of you in line, then you went and filed another case, and now you are filing this motion, you have complicated it a little too much for me to be able to provide you something within the confines of "general legal information" and I don't want to provide you with misinformation or an improper citation (giving you bad law for your case could actually hurt your matter rather than help - this is why we do not practice law on the forum (aside from violating our rules of professional conduct)).
You can generally find this type of information rather quickly in a practice guide - look for a probate practice guide in your local law library, ask the law librarian for assistance, they can point you to the proper text in their collection - it will have citations to authorities for various circumstances and as I noted earlier, will even have templates you can use to help you draft your motion.
I don't believe this will take too much of your time, but you really need to take the time to do it properly (go to the law library) in order to ensure that you don't have your compensation held up any longer.
(Many individuals representing themselves "pro per" (without an attorney) become overly reliant on the internet, hoping there is a quick solution, but if you are representing yourself, please realize that you must plan on conducting yourself like your own attorney - and attorneys spend a great deal of time researching each motion before they write it - which is what I am suggesting to you. Forums such as ours are helpful to assist you in pointing you in the right direction, but we cannot substitute for the time and money that it takes to conduct legal research and writing (the actual practice of law which we charge much more for in our traditional practice)).
