Don't use grease. Oil is ok,as is assembly lube, but dont grease it.<br />Rust is normal on the shaft. Be only concerned with rust or pitting under the portion where the seal rides.<br />Pressue test the lower unit before putting it back on, to make sure it is sealing . Look for 5-10PSI in a barrel,or garbage can of water,(l/U submerged). There should be no bubbles.
