1) You can use naval jelly (it's pink) to remove the surface rust, or you can use a High Temp rust converter and just spray it on. It will convert the existing oxide to a flat finish. You can leave that flat finish there to protect the block from further rust.

2) Always use plastiguage to measure clearances/tolerances. Just because something is new doesn't mean you shouldn't measure it. Saving $10 on the front end can cause you hours and $100s in aggravation later on.
