1 and 3) Strong acids and strong bases will fully dissociate so you do not need an ICE box. For some strong acid, however, you may still need some ICE box calculations since the conjugate base of the strong acid may be an acid (example: H3PO4 --> H+ + H2PO42-, and H2PO4- is a weak acid).
2. The main difference will that the equivalence point is no longer at pH 7, so you have to use an indicator that changes color at the correct pH (or better, use a pH meter).
