Bismillah..
dear sister.. at first, i'd like to send my warmest & greatest GONGRATULATIONS to become a muslima.. i am really so happy to hear this

I am An Arabic Muslim -from Syria- raised in a good conservative family (alhmdulillah=thanks god).. i advice new muslims to learn the teachings of Islam directly from Islamic Centers, especially those centers that are raised & build via Suadi efforts. do you have such centers in your town? i do not know where are you living now, so, would you like to tell me your town or city name and in which state and country it is -so i may help you better?
now, let us say general speaking & basic information regarding your questions:
1- hijab: yes! it is required.
2-women' praying: women are NOT required to pray the prayers (5 prayers) in the Mosque. you can pray them in your home, work, school, ... or mosque.. the best place for women to pray in is their homes as the Prophet Muhammed said, but, at the same time, he did NOt prevent them from going to Mosques.
3- concerning praying in any language other than Arabic: I do not know. but you may learn them in English letters as follows until you learn arabic: example from Suraht Al-Fatiha (the first Surah in the Quran) : "Al-Rahmanul Rahiem * maliki yaomiddien*...", i wish i could pass the idea to you..
any way, as i said earlier: Islamic Centers are better than forums & sites because NOT all of them are trust worthy!! a GREAT site is
www.islamway.com but i do not know if it is for new to islam or not! a visit to it may be good..
waiting your reply concerning your city information to attempt to help you more.. and here is my email address if you need any thing wish i could help you in all what you need:
rashadsibai@hotmail.com (i do not know whether it is allowed here or not)..
take care..
