Estate administration in probate can seem like a maze if it's not done on a regular basis. There is nothing magical about using the same attorney as drafted the will (although it is a time-honored practice by certain firms to hang onto their clients' wills 'with a death grip' in hopes of getting the probate administration work). The validity of the will stands on its own and has nothing to do with the drafting attorney.
While the powers of attorney cease to be effective on your mother's passing, you should anticipate working closely with the attorney's office to administer the estate. Usually, but not always, the more the Personal Representative does, the less the expense in attorneys fees.

My condolences upon the loss of your mother.
It is a good idea to speak with an attorney for assistance in probating an estate. For small estates, the attorney's involvement may be minimal, but his or her advice may be invaluable especially if there are significant debts, or if there tax issues. They can also help you with the sequence of things. For general information, there are guides to probate put out by the Registers of Wills - if you google "estate administration in Maryland", I think you'll find a link (but it isn't a substitute for speaking with an atttorney.)
You don't have to go back to the same attorney. Frequently, it may be easier to use the same attorney as he or she may be familiar with the decedent's affairs, assets, debts, and intentions, and the attorney may have already noted any particular issues that might arise with that decedent's estate.
That said, there is no requirement that you use the same attorney, it is more custom than anything else, if there is no long relationship between your mother and the attorney who did the will.
The will should still be good, assuming it was executed with all due formality. The probate attorney can handle as much or as little as you want them to do. If you are organized and keep good records, there may be some benefit for you to do more, which would be more economical. You are also in a position to engage other helpers, depending upon the needs. Poor record-keeping, on the other hand, might not save money. In any event, you should discuss with the attorney what different options would be appropriate in your mother's estate, and then make a decision once you have more information.
Finally, you should be aware that the Power of Attorney and Durable Power of Attorney for Health Care are effective only during the lifetime of your mother, and with her death, are no longer valid. Good luck!
Finally, this is not legal advice, which is only provided after execution of an engagement agreement and review of pertinent documents and other information. This kind of public forum is not appropriate to disclose all information necessary to give legal advice, which is only given after review of pertinent documents and information and execution of an engagement agreement.
