That is the later centerbolt heads so the center 2 intake holes are not at the same angle. You can "hog out" the holes in the intake and use wedge shims on those bolts or get a different intake.

Why can't you use the pulleys from your current engine? Serpentine is nice, but not necessary (and IMHO stay away from CS130 alternators).

Without taking it apart you will have to use an electric fuel pump.

I don't think I would do anything special other than prime well with a drill and rotate the crank a couple times while doing it. It looks pretty clean to me.

I would not do anything with plugs?

Also, this is not a roller cam engine. Be sure to use a high zinc oil and follow the break in process to the letter.
