Read the FAQ, there are some details as to what spec is better.
More specifically, taking iIS before CF is bad unless you are totally undergeared and have mana problems (and in this case you should take Dreamstate anyway, so i'll suppose you don't have mana problems).
Put the OF point somewhere else, it's not doing you any noticeable good.http://www.wowhead.com/?talent#0xRbuqIscdIVhouZbxcub
It's OK if you only care for single target damage. I personally prefer to have more AoE talents available but that's in the realm of personal preference mostly.
Just a fix, Typhoon is usefull (ie a better use of a GCD rather than non-eclipsed wrath or SF) against Razorscale, XT-002, Auriaya, Hodir, Freya, and probably a lot of other bosses i didn't yet went against (ie i don't know the full strats yet), as well as every time you are moving and your dots are already ticking (and starfall is on CD if you have it and can use it).
It's not a core talent, but it sees largely enough uses in boss fights to be a worthy talent purchase (compared to the <1% dps gain you'd get from other dps talents at that stage) depending on your gameplay preferences, raid composition or whatever other factors you want to consider.
