Should I power the relays from the Arduino 5V pin?
Relay coils can draw more current than the Arduino 5V pin should supply, especially with several relays on at once. Use a separate 5 V supply for the relays, with a common ground to the Arduino.
Can I stack other shields on top of it?
Yes, the board passes its headers through so other Arduino shields can be stacked on it. Check for pin conflicts, since the relay channels use digital pins that another shield may also need.
