1) Typically, "typographical errors" will not result in a complaint being dismissed. Only if the typographic error resulting in suing or naming the wrong party, or seemingly attempting to sue for something which no one can sue for, or makes it impossible to tell exactly what the cause of action is, etc., would this usually happen. (And even there: the court can and often will allow parties  to amend or correct mistaken documents.)2) Obviously, if the amount owed is wrong, then even if you have to pay it, you only have to pay the correct and provable amount. This is something that you can show at trial, assuming that the error is not in your favor. (If it is, you may wish to consider whether to bring it up.) It's at trial that each side can put forward its proofs or evidence to establish who is liable and for how much.3) You say that certaini facts "clearly" are not true. However, determining which facts are true or not is, again, is generally something done at trial. Again, that's where you can show that the other party is factually wrong. Saying that their facts are wrong will not get the judge to simply dismiss the lawsuit.
