Assalamu Aleikum wa Rahmatullah he Barakatu sis!!!!
Im so happy that you are studying Islam, Alhamdulilah. Your so blessed by Allah SWT to have been guided to Islam. To think that Allah (SWT) chose you to be guided, is such a great and wonderful thing and I am so happy for you :) Masha'Allah, congratulations for wearing the hijab it is a very big step and just know that modesty is a trait that Allah (SWT) loves very much!!
How far away from Dallas are you? It has the most amazing Muslim community, great Mosques there also that I have heard of. Texas also has a lot of revert Muslims, so you will meet a lot of reverts there too Insha'Allah.
Don't be afraid to ask the Imam anything, he is there to answer your questions. No questions are silly when it comes to Islam, in the end you are just learning more knowledge which is highly valued in the Quran (the world "ILM" or "Knowledge" is the second most used word in the Qu'ran next to God). And if they give you any trouble, then don't take it personally, Islam is perfect but Muslims are not.
I also suggest going to
www.islamreligion.com, they have a live chat and thousands of reliable, authentic Articles about Islam.
If you have any questions or anything else, I remember when I was a new revert and I would be happy to help you in any way possible via the net, such as PMing or something.
