I filed EAD renewal last week
I filed my I-765 for EAD renewal by E-Filing on July 21, 2005. I got my Receipt Number immediately. I have used it to check my application status online.
1. According to the statement on my receipt (online stauts), USCUS takes between 60-90 days to process this type of case.
2. You can E-file it by yourself at:

Good luck!
