1.Can i play the Tier 3 mission without being tier 3
2.If i play Tier 2 and then Tier 3 do i get both the hammers or im stuck with the 3* one
You'll only get the mission rewards if you start from the very beginning, and then you'll only get the rewards (hammer + bomb) that go with that mission. So yes you can jump right into the T2 or T3 versions, but you will not earn the rewards of the T1 version on that run. One run = one set of rewards. You can see this on the mission description page before you launch to the ready room.
