I usually call myself an Anarcho-Communist. However, I'm not exactly sure what theory is closest to my ideals. So I will list all my ideals and I'd appreciate it if someone could tell me what I'm closest to.
I believe in a large amount of civil liberties. (abortion, gay marriage, legalization of recreational drugs, etc)
I believe that people should be allowed to own fire arms for self defense (mainly from the government)
I believe that a nation should be self reliant and heavy taxes be put on foreign made goods. I think corporate practices like outsourcing should be criminalized. (Does this make me a nationalist?)
I believe a nation's economy should be based on the welfare of the people, not on the profits of a few.
I believe that decentralization is important. I believe that a local government should have more influence over the people than the federal government.
Lastly, I've been influenced greatly by the workings of Kropotkin and Alexander Berkman.
I am also willing to answer questions to better assess what my ideals are.
Well, maybe I should still start from where the questioner is rather than go into capital, money, and commodity production. I'll go a bit into the state, since RP addressed this.

Well, given that your starting point for understanding society is 'people' and 'nation' and you oppose 'foreign' goods...
...and these concepts that you are using are 'nationalist' concepts, then the answer to your question is:
The theory which is closest to your ideals is nationalism.
You're mistaken to call yourself either of these, because 'Communism' requires you to use a theory based on 'class' and 'exploitation within nations', rather than 'nationality'.
If you live in the US, blame 'American and foreign bosses' and support 'foreign and American workers'. Then you'll be on your way to being a Commie!
