L2 EAD to H1B, H1B in RFE & EAD is expiring Soon -- Urgent

[mahemanin]

Hi,

 

I'm currently on L2-EAD and H1B Cap (Change of Status)  has been filed, however

L2-EAD is expiring on 19th Sep 2013 and my H1B in RFE status. Valid L2 visa till April 2014

 

Questions

 

1. Can I apply for my EAD extension when my H1B COS is already filed ?

 

2. My employer is ready to push the RFE into Premium Processing , even if my H1B approved and start is 1st Oct 2013, Can I continue working from Sept 20th to Sept 30th without getting my EAD extension approval ?

 

3. If i'm not eligible to work, can I take leave for those 10 days and join back to office on 1st Oct ? If not, should I resign the Job and the employer have to Re-Hire me back ?

 

Please advise..

 

Thanks in advance ..
