Do you have any tips of how to make the most out of a lesson with a community tutor? How to avoid stalled discussions, add some structure, make it less awkward?

I learn the Levantine 'Amiya (I didn't study fusha at all) and am looking for books (preferably e-books) that a novice can read. I tried searching for books written in Levantine Arabic but unfortunately, all the books that I can find are folk stories (like this one <a href="https://www.amazon.com/%E2%80%AB%D9%82%D8%B5%D8%A9-%D9%84%D9%8A%D9%84%D9%89-%D9%88%D8%A7%D9%84%D8%B0%D8%A6%D8%A8-%D8%A8%D8%A7%D9%84%D9%84%D9%87%D8%AC%D8%A9-%D8%A7%D9%84%D8%B4%D8%A7%D9%85%D9%8A%D8%A9-ebook/dp/B07CPHVV7W/ref=sr_1_1?keywords=%D8%A7%D9%84%D9%82%D8%B5%D8%A9+%D9%84%D9%8A%D9%84%D9%89&qid=1572068412&sr=8-1" rel="noopener noreferrer" target="_blank">https://www.amazon.com/%E2%80%ABقصة-ليلى-والذئب-باللهجة-الشامية-ebook/dp/B07CPHVV7W/ref=sr_1_1?keywords=القصة+ليلى&qid=1572068412&sr=8-1</a>) . 

Can you please recommend me a book (for grown-ups) that a novice who studies colloquial Arabic will enjoy reading? I understand that the majority of the literature is written in MSA. Is this a big problem for me?

In Arabic, what is the difference between تمثيليات and مسلسلة ?

Let's say that I tell someone something good about myself: I have a new child, got a new job, graduated, etc. The person says ماشاء الله

Is there an accepted response to this blessing?

In Arabic, when asking someone to wait, people use

إستنى شوي

or

لحظة شوي

Is is acceptable to use these phases with senior people, teachers, customers etc., or is it considered rude?

السلام عليكم ورحمة الله وبركاته

Let's say I want to greet someone in Arabic without any religious references. What are my options beyond the casual

السلام عليكم

مرحبا

اهلا وسهلا

What can I say to make the greeting "stronger"?
