h1b visa stamping chennai

[checool]

my h1b visa expired sept 04..due to some emergency situation i am now in india..my company has filed my h1b renewal on premium processing a week back..now my doubts are:
-hw long does it actually take for the approval to come thru?
-and in chennai, they dont have any appointment before jan 05? is there any way i can get an appointment before that? can i apply in delhi/calcutta? if so, what valid reasons should i give them for that? also is there any other way of getting an appointment other than online (ie thru tts visas)
-and after interview how long does it take for the stamping?
any help in this regard is highly appreciated!
