Writing a formal letter for request of unpaid wages

I'm writing a formal request letter for the money that my boss owes me. I figured the best route to take is to ask her a few times in person, send a formal request through certified mail, contact the Texas Workforce Commission and possibly go to small claims court if needed. I never was the best in English class, so I thought I'd get some peer review so that I could perfect my letter while I give her a few days to collect the money. So far I have this:

Re: Unpaid Wages
Dear Ms. [Boss's lastname]:
I am writing in reference to the collection of my paycheck. I was hired as a dishwasher in May of 2012 at the pay rate of $7.25/hr.
I have not received a paycheck for the dates of [dates] and was only paid partially for the dates of [dates]. I have not received payment for [x] hours- I calculate the amount of wages owed to be $[dollars], based on the hours and pay rate listed above.
On [date], I requested full payment of my unpaid wages from you, [boss's name], but I have not yet received it. According to the Texas Labor Code, I am to be paid in full by the next scheduled pay day in accordance with the law.
“Sec. 61.019. FAILURE TO PAY WAGES; CRIMINAL PENALTY.
(a) An employer commits an offense if:
(1) at the time of hiring an employee, the employer intends to avoid payment of wages owed to the employee; and
(2) the employer fails after demand to pay those wages.
(b) An employer commits an offense if the employer:
(1) intends to avoid payment of wages owed to an employee;
(2) intends to continue to employ the employee; and
(3) fails after demand to pay those wages.
(c) An employer commits a separate offense under Subsection (b) for each pay period during which the employee earns wages that the employer fails to pay.
(d) An offense under this section is a felony of the third degree.
Acts 1993, 73rd Leg., ch. 269, Sec. 1, eff. Sept. 1, 1993. Amended by Acts 1997, 75th Leg., ch. 1158, Sec. 1, eff. Sept. 1, 1997.”
Accordingly, in the event that I do not receive full payment of the above-referenced amount within 30 days of hereof, I shall seek to enforce all of my available rights and remedies in accordance with the applicable laws.
This is an attempt to collect a debt; any information will be used for that purpose.
Sincerely,
[my name]

Thank you for any help that you could give me!
