1. Yes but aren't you supposed to be still working for your employer during that time (unless taking a vacation?)
2. The employer has the right to file for an extension 6 months prior to the expiration date and anytime in between.
3. Cannot return while the application process is still pending and there hasn't been a decision yet. In that situation it's better not to leave the country or have employer file premium processing if you are he'll bent on leaving.

If you have a valid H-1B visa and you can prove you have maintained the visa then you are allowed to travel on the H-1B and H-4 visas after filing for the extension petition. There are obvious issues that will arise however if your extension application is denied after your current H-1B visa is expired so timing is important to discuss with immigration counsel.
