[LotR] What's the difference between the Moria orcs, the Saruman orcs, Sauron's orcs, and the goblins of the Misty Mountains?

Saruman's orcs, (White Hand) were Uruk-hai, able to travel in daylight.  They worked with but didn't get along too well with Sauron's orcs (Red Eye).  What was their relationship with the other orc/goblin tribes mentioned?

Were the Moria orcs allied with Saruman or Sauron?  Were they "working" for anybody, or did they just live in Moria?  Did they have any hatred or friendship with the goblins of the Misty Mountains?

All Orcs can travel by daylight, they just don't like it.  It's not like they'll turn to stone like Trolls.  There isn't any difference in "breed" of Orc, just merely who they're in service to.

The Moria Orcs seem to be largely just your generic unaffiliated Orcs.  That said, if Sauron gave them an order, they'd probably follow it.

The is no difference between orcs and goblins aside from the name.   

There *is* a difference between your generic Orc and an "Uruk-hai".  "Uruk-hai" means "Orc-folk" but in use is reserved for the bigger fighting specialists.  Professional Soldiers if you will (though obviously they aren't paid or anything like that).  The Uruk-hai call other orcs *Snaga*, which means slave.
