tier 2 dependent pay slips and letter from the employer

[hershey14]

Hi all,
I have some general question regarding pay slips and bank statements.
I am applying for a tier 2 dependent visa from India. My wife is currently on tier 2 general. She just started her new employment with her new company on 22/1/13. Her previous employment ended on 8/1/13.We have all the pay slips from her previous employment which also correlate to the bank statements which we r planning to submit.
my question is
1) would that suffice the requirement along with a letter from the new employer stating her new offer?
2) do we have to wait for a pay slip from her new employer?

Please advice me as to what we should do, your help is greatly appreciated...
Thanks
