Wired and wireless speakers won't work, won't be in sync so scrap that idea.
No offence here, but since you don't even know that the red/black thingies' are called RCA jacks, you may be in over your head to set this up. And are you doing all this, just for a single party or a party, and then afterwards, keep everything
Ceiling speakers aren't for "surround" in anyway. Now the whole house is wired, you'd have to rip open walls to wire in "subwoofers" so ignore that.
Are they powered speakers? What happens if you plug say a phone with a 3.5mm to RCA jack in to the red and black thingys and play some music?
