Hi salam20,
Can you tell us exactly what work experience you provided in your application? Also, you said you would get 66 points with just one year of work experience, did you include adaptability points for your wife's education? Depending on what she has, you can get up to 5 extra points.
About work experience, if my calculation is correct, you have around 3,100 hours for your experience back home (about 2,350 of which are continuous, so you're fine for minimum requirements) , so you'd need an additional 800 hours from RA/TA. If I understand correctly, you have 654 hours from your taxable RA from Jan 09 to April 10. And you have an additional 12 hours per week from TA in the period of September 09 to April 10? Did you include these hours with your initial submissions? If you did, then that should easily put you above 3,900 hours based only on your taxable RA/TA, and you have nothing to worry about, provided of course they accept your job descriptions and your foreign work experience as well.
The question is, once again, what did you provide with the initial submission? In my opinion, I think you should try your best to refrain from sending them additional documents unless they make a request for extra information. They may not consider it at all. As I said, the monthly award can be considered as 'salary' for RA (two of my friends got their PR through mostly non-taxable RA), even if it's non-taxable, but did you include it with your initial submissions? If you did, then they will consider it, provided they accept the descriptions. If you did not, then convincing them to add it to your work experience may be tough.
