What AC power adapter will plug right into this?

The recommended external power source for this board is a Li-Po Single Cell, 3.7V, 700mAh Minimum

What are the 3 connectors on the board? What wire do I need in order to program this thing?

The MKR 1010 is programmed using the mini usb port. The jst connector is for li-po battery external power & the 5 pin connector is for I2C access. Hope this helps.

What is the proper connector to power this thing with a battery?

The connector on the side you would plug a battery into is a JST-PH style connector.

Without eeprom, how to store the program (sketch)? after a power off and restart, data on ram is lost.

The sketch will persist between reboots, but any volatile data in the RAM will be lost unless you include the EEPROM emulator package. The emulator will write to the EEPROM in which the program is stored at the cost of device life. The process significantly reduces the number of times you can write a new program to the Arduino.
