Gone In A Flash, Lightning Greaves, and Lightning Press

[long bear]

If I Lightning Press a Gone in a Flash with Lightning Greaves active and bounce the Gone in a Flash, will I gain an action point or does Gone in a Flash bouncing fizzle the go again?

If you do it before the damage step (reactions, attack step, defense step), you dont gain the action point from the go again.
Edit: refer to matthew and dylan answer

Lightning Press requires a target. Go Again on Lightning Press will not resolve because the card no longer has a valid target (this is assuming you play it before the damage step)

If played during or after the damage step, Go Again will resolve (but GIAF will still only deal 4 damage)

Even if you do it in the damage step, lightning press won't resolve since the target is no longer legal

I guess I was thinking in terms of LKI but that’s right. You can’t target LKI

Those two cards literally just don’t work together lol

[storm elbow]

you can lighhtning press a previous attack or an opponent's blocking attack action card

You can also press gone in a flash while it's still a layer. It won't bounce and you still get an action point

Is it because of 8.3.5a ? It's considered a non-attack layer at this point?

[storm elbow]

you can press gone in a flash in the layer step because it's still an attack action card while it's a layer, and when a card moves from the stack to the arena is stays the same object.
Gone in a Flash's bounce ability is an attack trigger that sets up a delayed trigger, so if you press it before the attack trigger resolves, there's no interaction with the delayed trigger
