what functions does the bootloader provide after reset?
move flash to 0x00000000?
run adc self-calibration cycles?
after a flash page is erased, what value is returned if we read a memory location on that page?
The ram is not zeroed.
Erased pages have all bits set to 1.

Yes, this is as it is explained in the data-sheets of the individual ADuC7xxx parts.
But is does not run a calibration, it does restore the factory-calibration data.
For Flash handling please refer, depending on the specific part you use, either the UART- or I2C-Serial-Download-Protocol - outlined in the AN-724 or AN-806.
