Want a Bengali conversation checked

I am in the process of learning Bengali and I also have a Bengali teaching website (http://gobangla.web.officelive.com) that covers some of the things I have already learned. I want to start adding some simple conversations to the site. I will put the first here. I think it is correct because I have pulled it from a few books I have. I didn't know this:

What do you do? apni ki koren?
I am a____ ami ____
I am a teacher. Ami akjon shikshak. ("ajkon" means "1" :: I am "a" teacher) "a" in akjon to be pronounced as "a" in "about" not as "e" in "bed"...

I would also really like some help adding things that might realistically come up in a conversation with people meeting for the first time. I would appreciate your help.

How are you? kamon achen "a" as in "about"
I am good bhalo achi ... or "Ami bhalo achi" (ami = I)
What is your name? tomar nam ki?
My name is____ amar nam____
What do you do? apni ki koren?
I am a____ ami ____
Where do you live? apni kothay thaken?
Say it again. abar bolun
Where do you live? apni kothay thaken?
I live in_____ ami _______ thaki (Ami United States e thaki)
How old are you? apnar boyosh koto?<em> (koto:: first "o" is like "aw" as in "of"/"hot", second "o" is like the english "o")</em>
I am ____ years old amar boyosh ____  (amar boyosh dosh bochhor:: I am 10 yrs old)
Who is he? tini ke?
He is my friend tini amar bondhu
(or <em>she amar bondhu</em>) ("e" as "e" in "bed")
<em>Basically "she/se" means "he/she"</em>
