Q1: If I place 1 Shuu Yulin from my hand as this Digimon's bottom digivolution card at the start of my main phase, does this card's effect prevent it from being affected by the Security effects of my opponent's Security Digimon?
Yes, it isn't affected. Security effects on Security Digimon are treated as Digimon effects, so the "this Digimon isn't affected by the effects of your opponent's Digimon" effect prevents such effects from affecting this Digimon.
