If a player goes invisible (any of the five senses described in the power description) can a zombie easily spot them because of their thermal vision? Can other heroes easily spot them with any of their super-senses or enhanced senses? If they can indeed spot them, is their a perception action roll against the invisible heroes' invisible action roll? Or does the enemy spot them automatically?
According to the power, once you choose invisibility for a specific sense, it apparently covers that entire spectrum. The GM might ask you to make a roll during a specific moment incase someone attempting to spot you with the sense (which you are invisibile to) has a higher perception roll than your power's passive roll. Mileage will vary.

On the same note, if an invisible player attacks an enemy while invisible, does that player get to add their ranks in stealth to their power action roll?
Normally no. Invisible characters that remain undetected to a target and attack him, that target is surprised (thus under the effects of Tactical Edge). Pending on the situation (and how well one rolled/remained undetected), the GM might add additional effects.
Hope this helps
