For your second question, yes it's the same as FS2004 for both bank and pitch.

default_bank_mode= This determines the default bank mode when the autopilot logic is turned on.
0 = None
1 = Wing Level Hold
2 = Heading Hold (current heading).
If no value is set, Wing Level Hold will be the default.

default_pitch_mode= This determines the default pitch mode when the autopilot logic is turned on.
0 = None
1 = Pitch Hold (current pitch angle)
2 = Altitude Hold (current altitude)
If no value is set, Pitch Hold will be the default.

or-

use_no_default_pitch=  Setting this flag to 1 will cause the default pitch mode to be "None". It will actually set the variable default_pitch_mode to zero, so that there is no default pitch mode when the autopilot logic is activated.
The preferred method is to set the default_pitch_mode directly. 

use_no_default_bank=  Setting this flag to 1 will cause the default bank mode to be "None". It will actually set the variable default_bank_mode to zero, so that there is no default bank mode when the autopilot logic is activated.
