You may not need a lawyer. For something like registration, you can avoid any conviction or fine by showing that you did have registration at the time the citation was issued. Just show it to the prosecutor and, assuming you had it at that time, it should be alright.
As for the improper placement, that's a judgment call that's up to you. Some people prefer to hire a lawyer simply for the sake of having someone who can speak to the judge in a professional manner and lay out your story certain way. If you feel comfortable talking to the judge, then you may not want to. If you prefer to have someone there on your behalf or if you're worried about wrong sticker then you may want to consider it.
In the end, it's up to you.
