Change in cirsumstances - Resigned before appointment date

Hi Gurus,
I have my tier 1 general extension due next fortnite.
My Visa is valid till June 2012 but I am going for an early application throught Premium appointment ( PEO Croydon) only for me and will be applying for my Dependent Visa ( Wife+1 kid+ one expected baby) in March 2012 by Post.
I would need few inputs from experience folks on the below subject as the guidence document does not Negate my assertion.
1. Will applying only for My extension weaken my case ? My dependent visa is valid till June 2012 and I intend to get there Visa application only in March 2012 . This is primarily due to my frequest travel plan and paucity of money for Premium visa processing fees.
2. I booked my PEO appointment last month . I am employed in an UK arm of Indian IT firm and would be showing income only from this firm . I have got sufficient funds and supported by Salary slips ( attested and stamped by Payroll) and Salary certificate from HR . Now the problem is on the day of Visa appointment , I WILL NOT be on role of this company ,as I have resigned and last day will be next week. I will be joining my next UK renowned organization only after 2 months. I am worried about what will be my Employement status to be written in application. I am worried if I dont divulge my unemployement status in the application form and the ECO checks by calling (on phone) my current organization , this will be a cause of trouble. If I divulge my Unemployement status will this be again weeken my case?

Looking forward tp your inputs .
Cheers
anand
