I have some answers regarding cracking in general, but your questions all seem to be about WPA, so I'll give you answers regarding WPA cracking instead.

For example, using a single, gigantic dictionary list means that you would probably spend a lot of time in each letter. Is a linear approach (going from start to finish) statistically better or worse than it being randomized?

Gigantic dictionaries never make sense. Using several smaller, probabilisticly-ordered wordlists is always the way to go. Randomized never makes sense, you want to try the most likely candidates first and taper off.

The dictionaries go from start to finish in (roughly) the same order every time.

Pretty much, except brute forcing WPA does not make any sense unless the key is all digits. And even then you better have an idea of what the key is.

Just use hashcat.

In terms of a dictionary attack, Hascat using regular dictionary files seems to be my best bet. Seeing as how Hashcat is GPU-accelerated and I have a GTX-690 (only one), this option seems to make sense for me. Am I wrong?

No, you are not wrong.

All of them.

Finally; my understanding of the process of Hashcat is to obtain a handshake by de-authenticating a client (I can inject), taking that file and converting it here using the online tool (why is that hosted online and not a part of Hashcat itself? - just curious), and finally, to run Hashcat with my selected Dictionary files.

You don't have to use the online tool, you can download cap2hccap. The download link is provided on the page where you upload your cap. Otherwise, this is correct.
