Dominion - bold and regular type: which action comes first?
You do exactly what the card says in order, how bold the type is doesn't matter. The +2 Actions isn't an instruction to play (up to) 2 action cards at that time, it means that later in the Action Phase you can play 2 additional actions. So the revealing cards would happen before you could play any other cards from your hand.

From the Dominion Rules:


  Furthermore, the player must
  fully resolve an Action card before playing another one (if he is
  able to play another Action card).


and 


  "+X Action(s)" – the player may play X number of additional Actions this
  turn. +X Action(s) adds to the number of Actions that can be played in the
  Action phase. It does not mean play another Action immediately. The
  instructions on the current Action card must be completed before playing
  any additional Actions.
