Luminen Shock does 1D10+3 Energy Damage with the Shocking special ability.

Since it's a melee attack, is the Strength bonus added to the damage total?

You have to spend a half action per turn to sustain Maglev Grace/Transcendence.

Is this wether you move or not, or have you to, in order to actually move, invest the other half action (as the Rogue Trader Rulebook seems to imply)?

Thanks

Considering it's completely touch-based and not an actual punch, I wouldn't apply strength.

I'd say it's the former. "You may move at your walking pace" would be irrelevant if walking was the only form of movement you had left due to action restrictions.
