I am making my first app and just signed and did all that to make a official signed, non debugging apk. Now, if I want to make a small change, do I need to go through all the resigning again, and use the same key, or what?

Yes, you must resign and you should use the same key if you want your users to be able to upgrade without difficulty (if you change the key it is considered a different app).

You should also update the version info in the AndroidManifest.xml file.

Yes. You need to use the same key every time you submit to the market. Make sure you keep your keystore in a safe place.

Yes, you have to sign with the same key to be able update the app on the market. further more, if you lose your keystore - you will not be able to update the app anymore. So back it up somewhere safe, and preferably on three more places.
