Excluding Kholi over Yusuf, Raina, or even Yuvraj and Ghambir seems bizarre to me. He's been excellent, why leave him out?
I've always considered it vital to have five front-line bowlers. Making do with part-timers isn't enough. If you need your #7 to make a big hundred you've failed. Lower-order batting is barely used, but even if you bowl brilliantly you need that 5th bowler. Dhoni at #7 is a waste.
I really haven't seen much of Yusuf's bowling. Is he an all-rounder or a part-timer? I'd be willing to give hime the benefit of the doubt.
Playing all-rounders at 8-9 is a big part of what got India out of the T20 this year, while playing 5 planned bowlers is a big part of what won it for them in 07.
