Bought some R134a refrigerant
Now, where do I plug into the system to put this stuff in?
On here, right? One of the white plastic screws?

You cant just use 134a in your car you need a adaptor kit and a/c oil.
The retrofit kit can be bought at most auto parts stores for $50.00 or so.
DO NOT CHARGE YOUR SYSTEM WITH 134a THE R12 IN YOUR CAR IS NOT COMPATIBLE.....
You must also purge the old refridgerant out of the system with an evacuation machine.

I'm no expert but my neighbor is 
(at least in my opinion) He says if you just dump it in, it will destroy all the oil seals and might possibly ruin the compressor. He suggested fully evacuating the system, then replacing all the seals with the right kind (kit has these seals or is supposed to). Then it should last for a long time. I'm not entirely sure what will happen if you don't evacuate the old refridgerant from the system first... but I do know if you don't change those seals it will be leaking from all over very soon and a siezed compressor might come next.
Buddy of mine did a conversion on a Trans Am and did it right, fully evacuated the system and replaced all the seals... I'm telling you that thing blew ice chips... it hurt it was so cold.

I've read lots and came to the assumption it's doable without any 'kit'.

The different seals in the kit is just because the 134a is finer and will seap out through the seals from the R12 right? If so, I don't care about that because it just needs to work for a few hours. And from the looks of it I don't need the adapters in the kit to fill it up. So the kit, when considering that, is rather a waste for me right now. All I wanted to know was where to put the stuff in.

You would dump it in the fitting marked "S" for suction.
Purge the air out of the connecting hose by opening the valve on the can tap a little before you connect it to the compressor.
Mixing the refrigerants should cause no harm, but it is illeagal.
However, the 134a cannot carry the oil that is in the system to lube the compressor.
So thats what the oil supplied in the kits is for, to blend with the mineral oil and "try" to drag it around to lube the comp.
In a proper retrofit , you flush the components, replace the oil (with 134a compatable), and reciver/drier, expansion valve, and o-rings, vacuum the system, and charge.
If you get the oil (ester) in a pressurized can so you don't need to open the system, and add around 4 ozs. you will have much better luck than adding none.
Or do it right, I know everyone can't afford to, or rationalize the cost

I can afford the kit, I just didn't think it was completely necessary for what I wanted it to do (work for a few hours). But if it really is that much wiser to go with the kit, then i'll go ahead and pick it up.

I got a kit from autozone,
It came with the adaptors that you will need! Retrofit oil and 3 cans of R134a.
My system was empty as I had to crack open the AC lines when I rebuilding her, just let it go into the o-zone. Whoops didnt know that was illegal :[
I started her up and turned the AC on high, and put in the oil.
Then I put in the R134a
I had to wrap a warm towel around the cans they kept freezing up when I was dumping them in the system.
I was good to go. Blows cold! Now If I could just get my carb right I could run the AC and enjoy it
