Wa Alaykum Assalaam,
Regarding Muharram - the basic concept behind the fast is the same as any other, i.e. waking up before Fajr (the morning prayer) time to eat and breaking fast at sunset. Fajr beginning time is currently around 6:30 am, so it would probably be good to wake up around 5:45-6.00 am and finish eating before 6:30 Insha'Allaah. Maghrib, the sunset prayer, is about 4:08 pm on Monday, so that is around the time to break your fast.

Masha'Allaah, it's excellent that you are eager to start praying. As prayer is such an important part of Islam, it's essential to get it sorted out as soon as possible. Start with the most important aspects of prayer like surah Al-Fatiha. I know that for a person unable to recite al-Fatiha at all or is unable to learn it, or he has just become Muslim and the time for prayer has come and there is not enough time for him to learn it, then he is given a way out by
saying an alternative.

Second: If you have not yet learned the manner and characteristics of performing the prayer (i.e. at least the movements and positions), appended to this message is a description from which you can learn. What is requried from you for the time being is to say in the beginning of the prayer and between each movement between positions "Allaahu ak-bar" (a glorification of Allaah). While standing, bowing, prostrating, and sitting, you should say "subhaan allaah wal-hamdu lillaah wa-laa ilaaha illallaahu wallaahu akbar." (Glory be to Allaah, and praise and thanks be to Allaah, and there is no god but Allaah, and Allaah is the most Exalted and Great.) Then conclude the prayer by turning your head to the right then left, each time saying "as-salaamu alaikum."
This way of performing salaat is permissible for you until you can learn and memorize what should be said in each movement and position of the salaat.
It shouldn't be too hard to learn everything you need for prayer - keep trying and Allaah (swt) will help you.
