With Duct Tape I install and maintain duct work for a living if you want to seal the joints just wrap the tape around the duct. If you need to cover a hole you will need to screw a piece of metal on the duct over the hole and tape over the edges of your patch. this is the simplest and cheapest way I know to do it.

Why is your air blowing out cold air only through one vent?

The cold air is not getting to the other vents, this can have several common causes: 1. Too long of a run for the other vents. Air takes the path of least resistance, if the other vents are 20' further away they will have lower pressure coming through them. Seal the ducts and possibly add a booster fan. 2. Disconnected duct. Check all the lines, sometimes one gets disconnected and is blowing cold air into an attic, crawlspace, or basement. 3. Ducts are running through unconditioned space like an attic. If the duct work spends any time in a 130 degree attic, it raises the temperature of the cooled air. These ducts should be thoroughly sealed and some form of additional insulation put on top, R-30 to R-60. 4. Duct leakage. All ducts leak, often 10-30%. Seal any accessible joints with mastic (tile glue) or foil tape. Don't use duct tape.

Is it better to have vents in the ceiling or in the floor?

Does not matter. Air will displace naturally when pushed into a room from the vent. Vents and ducting are laid out according to the plans of the unit. That is the only reason for top vents and bottom vents. If you are speaking of the intakes, the same principal applies.

Why do you have exhaust vents in your ceiling?

When you say "exhaust vents in your ceiling" I assume you are referriong to the heating and AC vents inside your house and not the roof vent on the outside used to vent the attic. It is most likely that the duct work was ran in the ceiling for ease of installtion or the house may be built on a slab and they did not want to run the duct work through the slab.
