Ending a residential tenancy agreement

I have just paid my referencing fee for a new flat so I'm writing my letter to terminate the agreement on my current flat.
 
I have to give '1 calendar months' notice to the company from the date they recieve my letter.
 
This is how my letter looks...
 
    Dear Sir / Madam,
 
    RE: termination of tenancy
 
    I hereby give notice to terminate my tenancy at ...

    The last day of my tenancy will be Sunday 1^st March 2009. I will be available all day on that date to complete a check-out inspection.
    I will be due back my deposit of £450 within 14 days of the tenancy agreement coming to an end, subject to satisfactory inspection of provable damages.

    Prior to moving out I will ensure that the property is thoroughly cleaned.

    Please let me know asap if there is anything else you require me to do before I leave the property.
  
 
Couple of questions...
 
1.  Is that letter ok?
 
2. I currently pay my rent on the 2nd day of the month, so I've literally paid the following months rent today, as I pau up front, does that mean I can cancel the standing order for next months rent and pay them for the overlap (maybe one or two days rent?)?
 
3.  Is there anything I need to be aware/wary of in regard to it all?  The bills as I understand are entirely my responsibility to cancel/transfer them?
 
Any advice from those who've done it before is much appreciated, I don't want to overlook anything and lose money!
 
Editted for mistakes 

You're on a rolling contract then?

If so then the letter is fine.

It was fixed-term initially for 6 months, from which point I could give 1 month notice.  Currently in month 9 (moved in 5th May 08)

looks good to me

oh and any letters send them recorded delivery and keep a photocopy, just in case

Will do, ta.

I've also added a forwarding address (my parents address) to the above letter as well.

As for the standing order, I really don't want to have to chase £350 minus 2 days rent from them after I've gone, can I cancel the standing order and let them take the remaining from deposit or by some other means? 

Got a video camera?  I always film the complete house before leaving, as I wouldn't trust a landlord / agent on anything.  I've never left a place without them making some attempt at a deduction.

I could borrow my dads or take photos on a digital camera.
 
Doesn't help the flat was in rag order before I moved in, gashes in the wall were the previous tennant took furniture out, there are oil stains by the front door (look like a motorbike was kept under the stairs or something) and the windows on the front are cracked (I was told on 2 seperate occasions, once prior to moving in and once within the first month that new panes had been ordered and would be fitted but they never materialised).  I have the itenery grading list from when I moved in and it more or less confirms the state its in.
