Hm... Hard to say on the crankshaft seal, the "evidence" is gone... As to the cover gasket you might try cleaning it off real good with gasoline and then put it in the sun and see if it shrinks back down to size.
As to getting transmission in 5th, you will probably need to rotate the rear tire back and forth while shifting to get the gear dogs to line up, then it'll go into 4th and 5th. You'll probably want that while torquing the crank bolt back down.
As to the crankshaft seal, don't know what to say short of reassembling things enough that you can run the engine some to see if any "evidence" reappears...
