The card says:
Pulse Torpedo Attack 6 or Pulse Torpedo Shields 6. You can pay 1 Blue or 1 gold Data to increase this to 8.
Does it mean:
1. I pay 1 Blue to increase Pulse Torpedo OR play 1 Gold to increase Pulse Torpedo Shields
2. I pay either Blue or Gold and can then decide to upgrade either Torpedos or Shields?

Seems to me you first choose pulse torpedo attack OR pulse torpedo shields. Then you pay blue or gold to increase your choise from 6 to 8. So, I think your 2nd assumption is correct.
Thank you for confirming my suspicion. That's how altem mages work in MK. The problem is the attack symbols in Frontiers.
In MK you have
Ice -> blue attack symbol
Fire -> red attack symbol
Coldfire -> red+blue attack symbol
To boost Coldfire you can pay either blue or red, simple.
In Frontiers it is
Photon Pulse -> blue circle
Photon Torpedo -> red circle with yellow blotch
Pulse Torpedo -> red circle with slightly different yellow blotch
No easy way to tell what data to use for boosting.
