Witr and Nawaafil

Q: Can you please brief me on the different ways to praying witr salaah? and what is the niyah we make for the first two rakaah when we pray two rakah then one rakaah witr. Moreover, is it okay after returning to standing form (after ruku) we raise our hand reciting Dua Qunut and make dua.
