(i) It is mustahab (good) for the imam to turn right or left or towards the jama'at.
(ii) It is stated in a hadith, 'If a person says, "Astaghfirullah Al'azim-il-llazi La ilaha illa Huw-al-hayy-ul-qayyuma Wa Atubu ilayh", after every prayer of salaat, all his sins will be forgiven.
(iii) Imam and the followers raise their hands as high as their chest and pray (Dua) for themselves and for all muslims. A hadith declares, 'Prayers (Dua) sent after the five daily fard will be accepted.' (Tirmidhi). But the prayers (Dua) must be done with a vigilant heart. Not with fingers turned towards the qibla, arms not opened apart in the right-left direction, arms too close to each other, too far forward etc.
(iv) While saying Dua, the fact is that it is mustahab (good) to say salaat and salaam upon RasoolAllah (sallallahu alaihi wasallam),
(v) After making your Prayers (Dua), it is sunnat to rub the hands gently on the face.
