Yes you can use your previous approved visa stamping. No problem on that. At port of entry usa show them your previously approved visa and new I 797 approval notice. They will give you I 94 dates based on your current I 797.

1. Yes

2. No

1. You can enter with your previous visa.

2. No. However, inform the immigration office at the POE that you have changed employers and be ready to show the new petition from the new employer.

I was in the same boat until April 2016.
