Depending on your budget,i would say yes to both questions. I checked my 418" alignment straigtness before it went to the machineshop,and i even installed ARP studs. I put the bearings in,torqued it down and there was no binding and it felt good,so i did not have it align honed. I would definately get it decked though,although you could get away with that also,if the deck is within tolerance and you are not running a lot of compression.
