Because I busted a flat today on my way home from baseball practice (and I had to shoulder my steel-frame bike all the way home), I am seriously considering getting a seatbag... what should the contents be? This is my list thus far. Also, could anyone reccomend a good brand, or at least a good sie of bag.

Extra Tube
Patch Kit
Tire Iron
Small Adjustable Wrench
Allen Key set (not in the bag, as I have an old set that can fit in my pocket, along w/ a presta valve adapter)

Then I have to consider how to pump up a tire... should I get a bike mounted hand pump, or one of those CO2 pumps? How expensive are they, and are the refills expensive too? Thanks in advance.

I just have a tube, tire levers, allen wrench. Frame pump on the frame.

I use a 2nd waterbottle to hold my spare tube/tools.
I prefer a frame pump, can inflate as many flats that
I get plus I don't feel bad lending it out to fellow riders.
Which has happened a few times.

Tube, patch kit, all relevant allen and box wrenches (stripped from a multi-tool), tire levers, chain tool (also stripped from a multi-tool), bit of a tyvek envelope for a boot, and a patch kit box first aid kit (a few big bandages and Exedrin, for those poorly timed migraines). Frame pump on the bike. I also try to keep a $20 somewhere handy, just in case, but more often than not it ends up being spent.

That seems like a good idea. I need to bet a bottle and a cage anyway, So I might as well get two... but do you have any problems w/ rattling from the bottle? How do you stop that from happening?

The spare tube acts as a filler, I also have latex gloves in the bottle.
Everything is squeezed tightly. No rattles.

Pretty much what everyone posted up here.

For commuting I carry the following.

Bike mounted pump
Multi-tool (bike specific) that has tire levers incorporated into the design as well as a chain breaker.
Multi-tool that has pliers and knife.
2 spare tubes (lightweight tubes, i.e. compact)
patches
presta valve adapter

On my worst day I got a flat in the morning commute. After patching it up, I started to pump air and the damn valve stem broke on me (hence the multi-tool with pliers). On the way home I got another flat, but didn't have patches on hand so I had to use my last tube.

As for the chain breaker, a co-worker had to help another commuter with a broken chain and the tool came in handy.

I go along with what everyone else said, but would like to add that I prefer the Mini-Morph or Road-Morph pumps, as instead of the pump attaching right to the valve stem, the pump has a short hose (really a piece of plastic tubing) that goes between the pump and the valve stem. This prevents possibly ripping the valve stem out of the tube (which I gather is what happened to you in your first post).

The advantage of a pump over a CO-2 inflator is that the pump never runs out of CO-2 cartridges, and I don't feel like that you can control the amount of gas that goes into the tube as well. The CO-2 inflators are mainly intended for racers, anyway, and not really necessary for everyday applications.

I also carry a few electrical tie-wraps as well as a pocket knife. Don't really know why, except that the tie-wraps might come in handy, and a knife is just one of those things that, if you need one, you need one badly!
