The first can be done by setting input B to Item List, Gate C to GREP, and input A to the name of the item you want to check for. This will be the default, non-Id'd, name. Change Normal Chain to Conditional Chain and check the 'Chain if result True' box. Then add a chained event to the True chain for this logic block event.

I don't think number two can be done at present. The Logic Block is meant to be adaptable to designer needs, so I'll work out a way to make number 2 happen using Logic Block.
