You can't take a 5' step and move normally in the same round, but I'll say you can grab your swords as part of your move action.<br/><br/>And it's not really going to group initiative, just that all three of you act before any NPCs (just Marc, in this case) can do anything again, so it doesn't matter who does what first.  Next combat though, I'll average party initiative so you'll all act together.
