I am glad to be of assistance.

The steps are much the same as the explicit, except there is not INIT-UPDATE/EXT-AUTH commands to deal with. When the first secured APDU is received (CLA = 0x84), you follow the process to generate session keys and verify the MAC. The card spec outlines how to generate a MAC with the session keys.

When you load any code into ROM, it is harder to update again. But when the code is loaded into EEPROM, it can be updated any time. For development purposes you would like to use EEPROM to load the code.

There is no way to write track2 on java card, due to the data structure difference between magnetic stripe card and java card.

Of course you can. Keep in mind that crypto key is just a string.

You don't need to use Session Key. It can be a static key or a dynamic session key. It doesn't really matter as long as it is the same on both sides.
