With the combat talent build you have there, putting points into 'coup de grace' is a complete waste as a rupture rotation - through my own testing, and what seems to be, from the number crunchers, a bit better then an eviscerate rotation.
Similarly to feral druids in wotlk taking talents to buff Ferocious Bite, despite them not using it very often, it is still a dps boost when you do use it. I expect a combat rogue using a rupture rotation still uses Eviscerate quite abit.
According to elitistjerks, the difference between a rupture rotation and a non rupture cycle is approximately 2%
EJ further points out that, on complicated fights, where your target uptime might be less than perfect, dropping rupture could lead to an overall DPS increase due to the simplified rotation.
I assume the two points in Coup De Grace are needed to reach the next tier of the assassination tree - deadly momentum is far less useful in a raid encounter than more damage on eviscerate for a combat rogue.
Correct me if I am wrong Zaev, but I reckon that's probably why the points were put into Coup de Grace.
Looking further at a world of logs report for a combat rogue on Cho'Gall: [url]http://www.worldoflogs.com/reports/1smw0j5st98otp8t/details/27/?s=8530&e=8970[/url]
We can see that Eviscerate is responsible for a slightly higher proportion of his damage than Rupture. Arguaably therefore, the points put into Coup De Grace are justified.
