I will not touch base on the rear facing beyond one, as it seems it was well covered.
So instead, I will just reinforce what some others have said.
Be SURE that the chest clip is placed in line with his
ARM PITS. This will keep the harness straps on his shoulders and
prevent him from being ejected.
More importantly, be sure that the harness is tight enough. Many times, parents think they are tightening the straps enough when really they aren't. You should pull all of the slack from the thigh area, and then tighten. You should not be able to pinch any of the harness. It should be "as snug as a hug".
When
rear facing, the straps should be coming out at or
below the shoulders.
When forward facing (though it does not apply in your case
) the straps should be coming out at or above the shoulders.
Again, repeating the coat problem. You should never use a bulky coat with a car seat. When using bulky or thick clothing, in the event of a collision, the forces of the child moving will smush down the clothing. If the child is wearing bulky clothing, the thickness will "disappear" as it smushes down, creating extra slack in the harness (think about the space saver bags
). The extra slack could possibly eject him. When putting a child in the car seat with a coat, you can use the coat trick. See the video below.
You can also, like a previous poster said, use a thin jacket such as fleece. To be able to tell if the coat is too bulky for the car seat, put the coat on the child. Buckle him/her up as if they were just wearing normal clothes. Tighten appropriately. Now, without loosening the straps, unbuckle & take the child out. Take the coat off & put the child back into the seat (without loosening, so that the straps are still tightened to how they fit when the child was wearing the coat) & re-buckle. If there is extra slack in the harness, it is too big.
However, *I* feel it's simply better (no room for error) to just buckle the child into the seat without his/her coat and bundle them up with blankets, mittens & a hat. I would recommend no coat. Here is an awesome video demonstrating the "coat trick":

Just some tips to make sure your installation in the vehicle is good.
**Another thing that I want to mention that many parents don't know about. When installing your car seat, be sure to use either LATCH OR the seatbelt. You can not use both. They are both equally safe, just cannot be used together.
Statistically, the center is the safest place for a car seat. It is roughly 3-5% safer than outboard. However, it is
only safer than riding outboard if you get a good, tight install. -- Meaning no more than 1inch of movement.
Also, regarding center installation. Many vehicles do not allow you to use LATCH in the center. If you do not have three separate sets of LATCH anchors, you might not be able to install with LATCH. Before you install in the center with LATCH, be sure to
check your vehicle manual. If you cannot install via LATCH, seatbelt is just as safe.
Be sure to
lock the seatbelt! This may include: using a locking clip, having locking latchplates, or the most common-- pulling the seatbelt all the way out and allowing it to switch over to locking mode. It will ratchet as it tightens. All vehicles after '96 are required to have seatbelts that lock in some way. If you aren't sure how your vehicle's seatbelts lock, check out this link:

The car seat or base should never move more than 1". Extra movement could be fatal in the event of a collision.
You should never use anything underneath a car seat installed in your vehicle either. Are you afraid of ruining your seats? Use a
thin towel. Shelf liners use to be recommended, but no longer are. They may give a false sense of tightness. They have anti-slip materials, so when you think your car seat is installed tightly, it really may not be. Not to mention the fact that they can melt onto your vehicle seat.
I think that's the main stuff!
