First, you are going to need an attorney. Contesting a will is not an easy process, whether you are claiming undue influence or lack of capacity. YOu would need to file an action in the probate case and there are strict time limitations on how long you have to do this. Don't wait. Contact an attorney now.
Unfortunately, you are an investor. While it seems that your parents left you "money", in fact they left you their investment account in the mortgage investment company. You'll need to see a probate attorney about this, and probably one who does probate litigation.
From what you have stated, "lots of property, bank account", it is almost certain the estate will have to be probated. If there is real property, it will certainly have to be probated. If there is no will the property will be probated under the laws of intestacy. Probate can occur in a number of places, depending on the specifics of the circumstances. It may be probated in the state where he died, in the state where he held legal residence if that is different from the state where he died,...
Under Colorado law, an agent under power of attorney would not have the right to change the terms of a person's will, including not having the right to change the personal representative (aka executor) named in the will.

I don't really understand your final sentence. Under Colorado law if there are two personal representatives named in the will, then they would both be co-personal representatives and both liable for completing the...
Under the Uniform Guardianship and Protective Proceedings Jurisdiction Act (which may or may not be in effect in your state. I believe it is in effect in Alabama.) his "home state" is still Utah and you can petition for guardianship in the Utah court. IT is not his intention to establish residence in Alabama and he has been there for less than six months. Apply in Utah.
Agree with Ms Shaffner. Your mother can grant a life estate in the property in her will, or she can pass the property to a trust (either a revocable living trust or a trust created in he will) specifying the stepfather's right to the use and enjoyment of the house until he dies, at which time it can pass to you.
She can try. Whether she can do so is another question. She would most likely file a complaint with adult protective services and they would investigate. To have you deported some illegal act must take place and it is up to Immigration, not the social worker to deal with this.
