Some advice on a S 2,29CT SI2?

Hi Folks,

New to the forum, but have read many posts here and seems like a great place for advice.  So, now it is my turn to ask:

I am considering the diamond described below for my girlfriend's engagement ring - set as a single solataire.  It seems like a great peice and the price is certainly below similar 4C diamonds I have found - here are my questions (and many thanks in advance for your advice!)

1.  Should I be concerned about the fact that it is lower cost?  Price here is about $9,000 per/ct.  Does that seem right?  The cert is from late November 2008 - is there any chance that diamond prices have come down of late leading to the lower cost as it may have been cheaper to acquire (I may be reaching here!)
2.  I have not seen the diamond (found online), and as you can see, the report says "additional clouds not shown" - how mcuh should I worry?
3.  The stone is AGS certified and the picture on the cert shows very faint small clouds in the center of the diamond - should I be very concerned about the location of them as they are under the pavilion?
4.  Additinal facet?  should I be concerned?
5.  What are your thoughts on the proportions?

THANKS again for thoughts - I really appreciate it!
