You can also download a key directly from a public key server if you know the ID. There are detached signatures and attached signatures.
Attached signatures are single files that include the original file and the signature combined. Detached signatures only include the signature, with the original file being separate. You will find all the uids e-mail addresses of the person who signed the key, as well as the people who have signed that key.

You did nothing wrong. The signature is correct, but GnuPG could not verify the key's validity, thus the signature is not deemed valid. With other words, GnuPG explains you that while the signature is issued by a totally valid key, the key could have issued by anybody you can create keys for arbitrary mail addresses, there is no central instance verifying them, especially key servers do not do! You need to search for that ID on the linked site, or another keyserver interface, using 0x8DA in the search box.
That site doesn't say that, although others do, and the instructions you followed didn't specify that. The site your gpg accessed to retrieve the key has a web-based interface, and it does say to use the hex notation when searching for a key by ID. BTW: Whenever working with obvious, or even possible, hex values; if one way doesn't work, try prefixing the "0x" to the number and test again. Your next step is confirming the key from an independent source, as the instructions you followed said.
The idea behind getting the info from the linked keyserver is to find the other signers of the questioned certificate, and try to find a path of trust from those you trust to those who trust the new key. Lacking that you can try "out-of-band" contact with a signer of the key to verify it.
