Put all info about your car in signature. 4/6 cyl, auto/manual, LX, DX....
Read fist post on this forum that covers this info.
I would treat the 3 lights as unrelated right now. You should start with the check engine light first, as this is the easiest to have checked.
I would disconnect the battery, then I would clean all ends of both battery cables. Once the check engine light returns, I would have the codes read at a parts store. I would also have the battery, alternator, and starter tested while you are there as well.
