If you plan on watching Night, you should definitely watch it first, both for spoiler reasons and for quality reasons.

If you've never seen any Fate anime, Night is not too bad. But Zero and UBW are just so much better that you'll end up being disappointed in Night if you watch either of them before Night.

So either leave Night out completely, or go with Night->Zero->UBW... and maybe Heaven's Feel if it's ever made. ^^

Oh and you probably want to avoid Kaleid Primer Ilya (or somesuch)... it's terrible.

If you want to fuck your mind in an amusing way, check out the Carnival Phantasm OVAs. ^^
