Please help with my tax return, Thanks a lot!

I am on my OPT now. I received 1042s from school and W-2 from the company I am working at now.

I started working since last Oct. I need to file 1040NR-EZ with 8843.
I have several questions.

I can claim treaty dedcution only up to the amount on 1042s or I can claim $5000? If there is only $4000 on 1042s, can I deduct the remaining $1000 from my W-2 income?

On 1040NR-EZ there is one place I need to indicate my occupation, I should put student since I am holding F-1 now or I should put my job title there?

Thank you so much!
