Hang on a sec, I left a step out of the merging process. Here's the whole thing from start to finish:

"To combine Part 1 with Part 2, copy the "arc.nsa" file from your MGQ Part 1 folder. Paste this arc.nsa file into Part 2's folder, choosing "Yes" to overwrite the current file.

Once copied over, launch MGQ Part 2 and go to the "Extra" Menu. In there, choose "Part 1Converstion". If you copied over the arc.nsa file, it will complete successfully. Once combined, monsters from part 1 are available to view in the encyclopedia. "New Game" will also now start from Part 1, at the very start."

Did you remember to do all that stuff, too?
