Most important ... talk to the employer's immigration lawyer, not a manager, not a para-legal and NOT a person in HR.
a. The I-94 controls people inside the US. The visa is only important when a person is outside of the US and wants to enter the US
b. That is probably correct
c. Possibly, talk to the company's immigration attorney
d. Not necessarily. As long as you are fully obeying the L classification, they probably won't invalidate the I-94
I support your planning in advance and strongly suggest a personal meeting with an immigration attorney ..... sooner, rather than later.

Your employer needs to retain an experienced immigration lawyer, whether myself or one of my colleagues, to review all the facts, advise them, and handle the case.
J Charles Ferrari Eng & Nishimura 213.622.2255 The statement above is general in nature and does not constitute legal advice, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship.
