Not sure which part of New York City you need to commute to, but if you're working midtown, the bus and train will take about the same time to get into the city, (35 to 40 minutes).
The E Hanover stop is at the corner of Ridgedale Ave & Eagle Rock
There are more departure times available from Whippany.

Let me know if I could be of any further assistance.
Here is the bus schedule for the Coach USA # 77
According to the schedule, it stops at Ridgedale and Eagle Rock Ave, but you do need to check the route..
If you have a car, you have another option - you can drive and park,, for free, at the Livingston Mall (bus leaves from there, too), and take a shuttle service ($2.00 each way) to the MidTown Direct train in S. Orange. The train is around 35 min into Penn Station.
This new service just started in October, and is open to anyone who wants to make use of it!
