I personally haven't ever put one together, but I know there are 4 parts you need:

The screws
Top solenoid part
Bottom Inlet, Outlet part
Gasket

I imagine the easiest way would be to insert the screws into the top half, then put the gasket on, then place it on the bottom half, screw the screws in, and call it good. This may or may not be good, but I know with oil filters, you should put some oil on the rubber gasket part to seal it better, so adding a little oil to the gasket may help it seal better.

As for wiring, I do know how to do that! The attachment below shows a diagram I drew to help another team a while back. It has more information than you asked for, but it should still help you out.

EDIT:
From Daniel_LaFleur from a few posts down.

Don't add oil as some oils will attack the seals. Use a silicone grease like Krytox or a barium based grease like Parker O-Lube.

Rosie had a major pnuematics leak with our Norgren regulator, there made to handle 50psi but according to the manual we were allowed to set it to 60 psi, well didnt, we replaced it with the Monnier Regulator and our system works good. We further investigated why the Norgren had malfunction, and our conclusions were that this years regualtors were only hand tight and the outside was more of a 12 sided polygon than the many ridges of last years Norgin, anyway we replaced it to the Monnier and it works good

Did you follow <R98>, which requires a Norgren regulator before any Monniers?

Your wiring is correct of you want to use it to power 1 side or the other as long as your output to the spike is -1 or 1. Setting the spike to 0 will not move the spool and the valve will not change (this can be used to your advantage).

SMC valves also require 20 PSI for the spool move.

Is the grease required ?

No, but it reduces the chance that you will have a leak.
